AITA for telling my gf her reason was stupid/ nonsense

So let me just break this down, so I'm M29 my gf is F22 we stared dating September 16 2023. F22 Cames from a big family where the oldest sister is 43 but Shes her half-sister and Shes the youngest. before we judge her mom and dad age difference s 14 years, all the siblings are living in deferent country's so they are not a close family because her father has been racist in the past when it comes to the sister's dating options so the lady's don't talk to their dad. but the all keep in on WhatsApp, so myself and gf meet at work i was her manager we worked well together (so we all worked and stayed on sight) so we found ourselves talking a lot, mind you she is the one chasing me and coming to my living space and inviting me to the beach, i play hard to get , because I am awe of the age gape and that I'm her manager but that does not stop her after 3 months we start dating . in the first we talk openly about her age and that she still has a lot that she hasn't experienced so i ask if she wants to really want to date me seriously cos we are at deferent points in life , i ,ask her in the first 4 months of dating and ech time she says no she wants me i do this one more time at the 6 month mark and her answer is still ''no"' every is good. she tells her dad about us and she gets disowned by her dad we work throw that together, she meets my mom and i meet hers ,side note (we in south Africa she's white and i am mixed and adopted by a British/Irish family that got separated when i was 13 ) so fast forward to this year feb where I resin my job cos of office politics and my gf stays and works, we have a nice amount of saving so I not struggling but a lil worried coz i know how hard it is to find a job in this country, so i take some money after speaking to the gf to do my soccer coaching licencing well im doing that the gf gets an email from her sister saying there's a job opportunity in China , so we use the saving and i borrow money from my mother so that we can get her to China and on the 18 of June she lands in China and her sister is there waiting for her .

a week later she begins working as a afternoon teacher , well she is doing all this her 31 year old sister takes her out clubbing, drinking and dancing , just enjoy all of this and maybe for an 1hr some days we talk on the phone ( i am home with no money , still looking for a job ) but i motivate when she is stressed or talk her down when she is upset with something her sister Sayed, don't get me wrong she show me love to when she not working. this is where thing get a little much for me, we have our 3 year anniversary on the 16 of September this year , we chat every seems good she tells me about a staff party where she gets drunk with her sister and some of her sister's friends she ends up needing to be taking home , life goes on we chat on the phone ,13 day later she messages me saying she need some space and she feel like she putting a wall up i ask her why she tells me that her sister went off at here i ask why she dances around the question she finely tells me that her sister got upset coz shed been hanging around one of her sisters guy friends go to get coffee, Dancing together and just been alone talking her sister reminds her that she has a bf and tells the guy to back off , and she feels guilty about it. i why if this guy is just a friend i don't mind as long as there is no line crossed . she say no all that happened was a hug that night she had to be take home when she was to drunk , ok what's the problem? she says to me she thinks she needs space and a brake so she can experience the single life , im confused and i ask why now she says that she didn't get to do that much now she in a new country she wats to have fun with NSA, so i ask if this guy had given her this idea , no it just that she wants to do this , i keep pushing and she finally says she clicked with him and enjoys hang out with him , i ask if she like or has feelings for him she says yes but promise nothing happened but the hug but she felt something after the hug but she loves me and only me but she wants a brake so she can be single end enjoy it with NSA coz she is a lil worried that she might get drunk and kiss this guy and she knows that it will hurt me if she dose so shes asking if we could take a brake so if she dose make the mistake of kissing him she doesn't hurt me coz she know if it happens well we still together it will hurt her more that if we on brake. that's when I ask her dose she want to kiss this guy, she say no but she's worried that she might when she's drunk, i say bs she been drinking since she was 18 and never has she kissed a guy that she didn't want to well she was drunk i tell her that a BS excuses she has gone out many time and gotten drunk and kissed no one , she aggress with me and says , she wont coz her sister has spoken to the guy about her and I dating and to respect the prelateship, she starts to cry say she knows all this is hurting me and that we have always been open and this is her been open, a the she say it again that she just want to enjoy a single life style with her sister and friends she and that means we need a barker ( before she left for China i told her she can do anything she wants just no sex ) i asked her how dose a guy she has had a crush on for a month make her for get 3 years , she starts cry's again say that not wat it is she's been thing about this for 2 month or more before this guy came along, i ask her so you want to go out with your sister and her single friend and do what they do she say yes but she promises she won't kiss any one even if she's drunk she just wants to have a NSA brake at the point i say it sounds like you just want to go have fun with this guy and you kiss him and have an excuses or a rezone not to feel bad.

her: "NO i just want to go out there and find my true self without worrying that i am hurting you"
me: so you do what to sleep with other guys or kiss them

her: no i wont kiss any one i just want to try the single life and find myself

me: That is stupid if you not going to kiss any one or sleep with any one and i have said you can do anything just no sex why do you need to be single or on a break

her: so that I don't hurt you as much as if we wear still dating

me: no that is nonsense you want to have you cake and eat it if we take a brake is the same thing as breaking up and that 3 years down the toilet just to party and drink and maybe kiss a guy when you to drunk

her : i cant talk about this any more it upsetting me and im getting anxiety

pots the phone down. says nothing for 40 min then says " I'm going out with my sisters friends tonight we will talk later i just need to think about this brake thing.

she sent me some massages after saying that i will try find a way to in closed them, if I made her seem like a Hartless B she is not she has said she loves many times in this situation and that she is sorry but .. that is my biggest she loves me but I don't like the "but" so AITA ??
