Big fight because I rescheduled Valentine’s Day (M23 F23)

My gf and I have dated for a year now.

Here is some context. I’ve been working a job that has been making me extremely miserable and my gf knows very well how upset it has made me. I finally get a meeting/interview to possibly transfer out of my role to a new one, one that I’m a lot more passionate about. However, it was the morning after Valentine’s Day.

Well, I ask her if we can celebrate on the weekend, as I want to use the night of Valentine’s to be well rested and prepare for the meeting (I also don’t get good sleep at her apartment). She says fine, but feels bad since she was planning to cook something special for me. So she says she won’t cook anymore if we reschedule and that I need to make it up to her. I tell her I feel really bad and want to reschedule…and that I’ll even help her run errands to make the dinner. But it feels unfair to make it up to her since I should be able to prioritize an opportunity that will finally help me leave my job.

She gets passive aggressive and we get into a huge fight over text and it leads to her cussing me out and telling me to go fuck myself because I can’t understand how she would feel being alone on Valentine’s Day and that I shouldn’t be confused as to why I should make it up to her. And I’m mad because we’re simply celebrating Valentine’s Day on another day and that she should support me and try to understand my POV on how important this meeting is to me.

Eventually, she apologizes and says she was being too harsh on me. Then comes Valentine’s Day and she is clearly sad over text. I try to make it up to her by buying flowers and her favorite snacks and having them delivered to her apartment. Well I call her and she said she appreciates it, but ultimately questions my thoughtfulness and believes I did it simply because she asked for effort. As if it means less now. We then get in another fight, as I get frustrated with her not even giving me credit for trying my best to make her happy with this gift.

I was upset because I truly do a lot to sacrifice for her and she is making such a big deal when the one time I prioritize myself over her feelings, she thinks I don’t care. She apologizes profusely over text and tells me she was blinded by her emotions to give me credit.

I still feel really upset by the situation - any advice? I just feel like my gf takes me for granted.
