(M29) Post Valentines Day Clarity, coming with the terms that my (F25) gf no longer respects or appreciates my efforts. Does this seem like the end?

Hi reddit wanted to make a post expressing some frustration but also looking for some advice in terms of my relationship with F25 gf.

Valentines day was a huge eye opener for me, I had gotten the gf a gift she would really appreciate, something shes been asking for for awhile to help her organize her makeup area. Friday the day before I got out of work a little late and we happened to be selling an old device of hers to someone that wasn't really willing to meet on our terms, I knew she needed the money and made it work putting myself out being exhausted from a 12 hour day and consuming more fuel to make this work for both parties. I pick her up and she's already upset about me being off work about an hour later than usual and in a bad mood already, things are tense and awkward so to break the ice I ask her you got it all charged up and ready for the buyer to take a look? She tells me um no it's dead that's your job... So I say well that's going to be a problem you should double check that. Argument started, criticizing me about not being prepared when she had almost four hours to double check over the device but instead used that time to sleep and play video games. She struggles getting it out of the box powering it on and is being rude the entire time about something so little. Device powers up it's right where I left it after restoring it, charging it up and powering it down then she proceeds to tell me how stupid I am.....

Silent awkward drive the rest of the way, we arrive only for her to hand me the device and have to meet the guy, do all the talking and the sale process. Seller buys we agree on a price money is handed over I get back into the car give her the money and she doesn't even say a thank you or nothing. In fact she then tells me oh I didn't bring my wallet with my bank card so yet again another trip to the other side of town and back at this point I'm ready to pass out from the long work day. We get to the bank and go through drive thru atm, she gets upset when I park beside it and have her go out to put the money in. Telling me that she shouldn't be the one freezing (Canadian winters) and how much of a 'little boy' I am for making her do so.... No thoughts or care that I have been working in the snow all day freezing for 12 hours while she was inside in her bed. To be clear she does not work, and never plans to so any conversation about her ever contributing financially is off the table as she will never work words from her mouth so it's all on me for some insight.

After the bank we went and got some groceries we get home and as per usual she tells me I'm hungry which is her way of saying get up and make food, for some perspective she does not cook or clean either so all duties fall on me... Hadn't even showered yet or got out of my work clothes and already demanding orders after we just spent an hour of driving to get her some extra money. She does not drive either by the way, so yet another duty on me. I make the dinner and go shower to start winding down while she proceeds to give me the silent treatment for showering without her.

Now comes Valentines day, due to my work it doesn't matter the day I am always up at about 7 or so. We made plans to go out to a fancy breakfast restaurant to which she slept in till almost noon and woke up demanding that we go and she's starving. We have our breakfast and about half way through the meal she gets a text from her best friend saying come over whenever you want to my sons birthday party, so now our expensive meal is rushed so she can go over there. For insight I do not like this person as just like the gf she does not work, scams disability income assistance and drinks and gets high all day, no ambitions what soever and it makes me so upset being there that I stopped going. Before dropping the gf off she says we have to run home so I can open my gift, yet again just worried about herself wants to open her gift then peace out. Opens her gift seemed like she liked it but again rushed as she had more important plans then the special day so I drop her off. I decided to go give my father a visit to which we had a nice meal and talk together before going to pickup gf to go to a movie. My dad really laid into to me and asked me why aren't you two spending the day together and I was dumbfounded quite honestly asked myself the same thing...

Pick her up and as soon as she gets into the car I smell alcohol on her breath and she's acting stupid, she then tells me that the kid was sleeping so they didn't celebrate instead she choose to drink with her friends then spend the day together and tells me that there gonna do a party the next day, which just so happens to be our three year anniversary can you guess which she chooses? To make matters worse, as a punishment as she says, at 1130pm vday she goes and has an hour long bath doom scrolling her stupid social media apps meanwhile we have to be up at 530am for some work help we obligated to our families and as soon as the 530am alarm goes off today she rolls over and says Ouch my jaw..... So here I am helping her family member move furniture early in the morning on my last day off while she yet again sleeps...

I feel like at this point the lack of respect and any care whatsoever to our relationship she puts out is making me go cold, the way she talks to me like I'm some person she hates, the way she has no care that I'm out five days a week 12 hours a day earning us a good paycheque while she sleeps just makes me feel like I'm being used.

So reddit what's your advice?
