Someone help!? Am I over thinking?

For the past month my boyfriend and I have been arguing about the stupidest things and there are days that we don’t talk at all than there are some that we talk but have the coldest conversation, some times we talk about relationship and where we stand but he always says that we made promises to stay no matter how tough situations were. But lately it seems that I bend over backwards to give him a hand while he doesn’t do much to help and when I ask for a favor he comes up with an excuse about how he can’t do it. I get mad and tell him stuff than he gets mad and leaves with to his brothers house who lives two hours away, and sometimes I don’t know where this relationship is heading. My parents never liked him because he’s been my first boyfriend for many years but I was super happy in the beginning of our relationship but now it just seems like I’m fighting to keep us together while he’s out with his older brother and his friends while I’m home trying to figure out what happened. I can’t talk to my mom about this because she’ll just given me the coldest conversation and my dad isn’t much about the boyfriend talk. And I don’t know where to turn so can you guys maybe help me out. 🙏🏻
