i (19M) need help with this girl (19F) am talking to

ive been talking to this girl online and we have been going at it for 4 months the first 3 months were amazing we flirted and got into really deep talks and it has been nothing but serious vibes

at first she told me she would never commit to a rls because of the unnecessary pain and the uncertainty of it all which is fine to me i told her i don’t want anything more if ur not up to it and told her that i like what we have now and we both agreed on that and tbh it seemed like a rls without a title and obviously me experiencing that i had always hoped that she would change her mind or smthn and id get to have her as not just a text buddy but as something more (ofc stupid me and i knew the consequences but didn’t care back then)

around the end of may everything went down hill i think if i had to guess why that happened is because apparently i got too “emotional” and to serious with things

one of those things that really broke us apart is when she started talking to this other guy out of boredom and started video calling him??, i know technically we aren’t dating and she isn’t at fault because shes “single” but am not a robot i have feelings and i feel like it was constantly brought up and i’ve told her many times am jealous over her yet she kept bringing it up and if i did switch my mood or get pissed am a baby and doing too much (to me it felt like she really didn’t respect my feelings with the way she was rubbing him all over me, yes she established she didn’t want a rls and we agreed we were nothing serious but what we had during those 3 months meant something and it just felt like she didn’t care and it was betrayal to me because the girl i knew back then would never do that and she didn’t used to do that until now)

anyways we got to the point were i told her lets be friends since she doesn’t like the idea of me getting too emotional and ofc she said yes (stupid me)
few days go by and we are drier than ever barely texted each other. i asked why she said we “fizzled” and theres no point in talking anymore (i feel like i typed too much so i’ll summarize)

told her lets stop talking (she agreed then said ill still text u tho) and from then we got better we started texting more and back to where we was except this time we were strictly friends
wanted to meet her for the first time and i did
picked her up enjoyed my time with her she was beautiful and it was just so much fun (although she did mention him again, but i guess she thought it was coo since we friends)
she cut him off and blocked him
although she still jealous baits and today she mentioned another guy so hooray

i need help in alot of things
• i can sense the manipulation and she knows how attached i am to her and id never give up, i gave her that confidence and she uses that against me.
• i just get really pissed off and disappointed at how shes acting sometimes like “leaving me on seen” “not watching any reel or video i send” “mentioning guys or jealous baiting and expecting a reaction out of me”
• the feeling of me chasing like a dog and shes in complete control is killing me

if you have wondered why i haven’t left is because am stupid and ik that
i used or still love her i know its ridiculous i’ve known her for 4 months but the level of deep emotional convos and the feelings that i kept on experiencing were too much and it won me over so fast and it did win her over at some point too (she always confessed her love to me but said she wouldn’t date and is too locked in to distract herself with that i never did say “i love you” because it was a promise that id tell her irl straight into her face instead of a text) anyways deep down am tolerating this new version of her and being me until she realizes that am worth it and am not some dog she comes to when shes bored, i just want her love i want to show her why i deserve that love.

but at the same time i feel like its time to leave and i want a good way to do it.

P.S:
• am sorry if i wrote this in bad grammar english is not my first language
• mb if it was too long
• if at any point i made her sound like the villain then its my fault i got caught up with my emotions but shes absolutely not shes an amazing women with great ambition and a complex character and all of those actions that i’ve been experiencing are all at my own free will and i could leave anytime but
i choose to stay and fight for her, and if it did sound like am a victim that got wronged then its false i do get a little too serious and emotional which ruins the vibe and i understand where people see that as somewhat “crybaby” ig
• and i absolutely understand how stupid and ridiculous is how serious i am about a girl i met 4 months ago but this isn’t stupid love i am sure of it i have never been more sure of a person than ever and yes i may have overestimated how “perfect” she is (no one is) but i still choose to stay.
