My relationship is failing!

Please help! Been feeling sad with my boyfriend lately to the point where of course my mind says it’s time to break up my my heart says to stay. Lately we’ve been fighting a lot and lately he has just been so mean. He’s always had a serious attitude and kind of doesn’t know how to be in a relationship. But I know he tries. My birthday was on June 26 and he brought me flowers the morning of my birthday which in our two years of dating he never has. It made me feel like the happiest girl. Sadly later on we went out to an area where they have a strip of bars. But when we got there he was annoyed at everything. I asked if he was okay but he snapped and told me how I fucked up and forgot the parking ticket. I told him that I was sorry and that I just thought we didn’t need it so I left it in the car. So he got mad at that, we tried to walk around but he wasn’t in a good mood so I asked him if he would like to leave and he said yes. I tried to give him space after he left my house. The next day we got into another fight for discussing political matters. Which I’ve told him before we don’t agree so let’s just not talk about it that way we don’t get into a fight. He said if we couldn’t talk about these simple things then what are we doing with each other. He said I wasn’t being considered with him and how my opinions need to be more thought through before I speak. We ended up working things out (I ended up saying sorry). but then this weekend after celebrating my birthday has just been fights after fights. We even went out on Saturday and he ended up drinking too much and ended up getting annoyed with me. (He even tossed a ring at me that I had bought him that day.) I just feel very alone because I try to fix before he gets upset but it just ends up failing. He even has been fighting with his mom and I’ve tried to either comfort him or give him space but he says I’m not helpful. I’m trying though each time I just feel sad that he says it’s not good enough. I’m sad girls I could really use someone to help me talk to I don’t want to tell my family or my cousin/Best friend because one I don’t want her to see him a different way and I don’t want Her to get annoyed with me.

What do I do? Should I try to be more supportive while he’s going through rough times or should I tell him we need space. Please give any more suggestions. Tell me if I’m wrong and I’m not being supportive just please give me advice.
