Breaking up with my boyfriend.

My bf and I have been together for about 7 months now and I’m starting to feel as though I’m settling due to not wanting to start over. I feel like I am constantly telling him how I want to be treated while going above and beyond for him. I know no relationship is perfect and I truly love and care about him and want a future with him but I have serious trust issues and he doesn’t even try to reassure me. When he does something that hurts me or bothers me I will try to talk to him about it but more times than not he will flip it or make me feel even worse for bringing it up. So sometimes I keep things bottled up just for fear of hurting worse. Sometimes he will apologize after the fact but it still hurts. Right now I’m just at my wits end and just want some advice. This week was his birthday and he’s someone who has a very unfortunate up bringing so I tried to do everything I could to make his day special. He is in the military so I drove out two hours to where he was stationed with balloons, a cake and candles, and gifts(iPad & lv wallet). He seemed happy and appreciative. We had plans to do dinner on the weekend then he decided to cancel bc his new friend (a guy) wanted to go to Nashville and turn up for his birthday. I felt disregarded but brushed it off because it’s his bday and he should spend it however he wants. But now that the weekend is over I look on his snap and see that it wasn’t just him and his guy friend his female friend met them there too. I feel some type of way because I don’t understand why he wouldn’t invite me. I spoke to him about how seeing that made me feel and he responded by saying “if you feel that way then fucking leave” and that I was trying to ruin his birthday. I don’t know if I’m overreacting by being hurt by this or what to really do. I didn’t want to ruin his day but I just wanted to be included. I haven’t responded to his text. Thanks in advance.
