Help?

April

My boyfriend and I have great times but we have been fighting more then usual like almost everyday.. and it’ll be a great day then he will get pissed off about something and start to pin things on me.. he can check my phone any times he wants but if I even look at his phone he gets furious. Yes we have talked about it but then I’m the bad guy and I honestly don’t know why..he says “ I don’t give you a reason not to trust me so why do you need to look at me phone?” And I’m like you check my phone anytime and I don’t care but it’s weird that I can’t even look at yours. I honestly don’t know what to do rn I’m just like stuck..help please?
