I 20/M, feel like I’m walking on eggshells with my gf 22/F

Apologies for any grammar, I am using voice to text.

Me, and my girlfriend, have been dating for about a year and a half, since then things have been mostly great, fun hangouts plenty of jokes and all of that stuff. The problem with this is, it only represents about half of the relationship. To get this out of the way, my girlfriend is extremely sensitive, she comes from an exuberantly wealthy family and has gotten just about everything she wants when she wants it. I, on the other hand was raised lower-middle class and have had to earn most things I’ve gotten, so I tent to walk things off a lot more. But this sensitivity drives me totally crazy sometimes. Whenever any minor inconvenience occurs, her whole mood totally shifts and it’s like night and day. This can be anything from having to go to work an extra hour to scraping a thumb. She usually takes out all of her bad mood and frustration on me, and not in a venting type of way, but by just being angry and hyper sensitive with me for hours.

Trust me, I’ve googled this problem plenty of times, and I have made several attempts at calmly and constructively voicing my opinion on how her yelling at me and taking out anger on me makes me feel. The problem is, whenever I bring up anything like this, instead of getting communication and understanding and apologies, I get nothing. Because of what I presume as sensitivity, no matter how nice or subtle I am about bringing anything up, if it involves how I feel about something making me upset, she goes fully silent. And by silent, I mean, literally not speaking and not responding to anything not even moving, which becomes extremely frustrating with me because I have no clue what I did to deserve this and for the most part, it makes me feel extremely unloved and unheard. I do a lot of things for her. I buy her gifts. I buy her food. I compliment her. I comment on social media post to all the things that a boyfriend is expected to do and I do a little bit extra on top of that. And whenever she takes out her anger on me that just makes me feel like extremely unheard and extremely underappreciated and I really just can’t stand it. I feel like every single minor thing that I might say or do is gonna upset her, which seems to happen more often than not.

I have one kind of boundary and that is that I hate being called annoying. Growing up, a lot of kids called me annoying, and it resulted in me basically staying silent between elementary school and high school and this is pretty much the only sort of upsetting trigger that I have, and yet it seems to be her go to. Whenever I do anything this could be talking about something that I’m interested in a little bit too much or just getting excited about something or just making a joke more than one time she immediately says that I’m being annoying and to stop talking and I’ve tried to voice to her how hurtful this is to me and how I really just don’t like it and it’s mostly because of how repetitive she gets with it. If it was a couple times I would definitely brush that off, but I get called annoying multiple times a day every day for a year and it comes extremely hurtful and it gets to my head sometimes and I’ve tried to explain this to her and it usually results in her being dead, silent or telling me “I don’t really care.”

I have a feeling that most of this has to be some sort of unresolved problem that has nothing to do with me because a lot of the times she also shows me how much she really does care about me through gifts, comments, and other things, but like I said in the previous paragraph this is only half the time the other half of the time she is extremely sensitive to just about anything that could happen and I have no clue what each day or even hour can hold. Her bad moods ended up with me feeling insulted and when I try to talk to her about it, it makes me feel worse because she will never communicate with me about it. I know it’s easy to just type in a comment section to break up with her, but I would like to illustrate that. I really do love her and I really do care about her and I’ve built a huge part of my life with her so any sound advice would be helpful obviously if you say to break up then go for it by all means. I just don’t really understand what course of action I should take. Would it be ok to try and talk it out?

TLDR: My girlfriend gets upset extremely easily and I end up getting anger taken out on me. Because of this I am extremely weary on everything I say and do around her, which I feel takes away from my happiness.
