Hello. I have been in a relationship with me 20(F) and my girlfriend 26(F) for 3 months now. I love the way she treats me and at times I feel like she treats me better than all of my past partners. We are currently long distance and plan to move in together next summer when her internship ends. She is super sweet and I love having someone who can make me laugh and feel loved lots. There is just some problems I am very concerned about. For one, when I do something small to make her upset, she tends to give me the silent treatment and act differently for days. She will be dry and give me barely any responses by saying things like "Idk" or yes and no answers only. Keep in mind this has happened around 3-4 times during the time we have been dating. On basically every occasion this happens in, the conversation/argument ends with something like "My feelings are hurt and that should matter more than who was right or wrong."
One of the times I accidently referred to her as a friend to some random in a game and she threw a fit and treated me like the times I mentioned above. It was a total accident and I got accused of not seeing her as my girlfriend. It was very emotionally draining and hurt me a lot at the time.
Another time, me and my friends were talking about pet names for friends and partners, and I told everyone that I almost called my friend and my cat, "babe" because I got used to saying it so much. To me, I thought it was just a silly little thing to make other people, including myself laugh. To her, she flipped out and accused me of comparing her to a cat, and told my how embarrassing it was, and we had a fight for a couple hours about it. I apologized profusely over such a small thing. Mind you I don't think our friends even cared.
There was a couple other things but I think you get the point. I would also like to add, when we would fight, she would throw me into 8 hour calls with her, and she REFUSED to engage in conversation with me, then when she would play games with her friends (when she said no to me and yes to them), she would be very happy and giddy, but quiet and silent with me. Also, during these fights, I tend to have this problem where I apologize even if I know I'm in the right. It's came to huge paragraphs, or just apologizing for 30 minutes for these tiny accidents. I know I should not but I have people pleaser syndrome and want everything to be okay even at my expense. XD, This would usually end the argument and she would treat me right again. XD
Also, as embarrassing as this is, I am sexually unhappy. I enjoy being sexual with her, but I guess it's not the exact way I would like it to be. I won't get into extreme detail but yeah.
TLDR; I like my relationship with my girlfriend but there's a few things bothering me that are making me very worried. She seems emotionally sensitive and I'm not as happy as I would like to be with us as a couple. We have fights every now and then and they tend to hurt us both pretty bad. My questions are, is this too big of a red flag for me to avoid? Is there anything I could do to improve our relationship? Should I break up with her?
