Idk anymore

Me and my boyfriend 2 years together and fight everyday. Everything about him now irks the fuck out of me. I dont want him touching me, talking to me etc. Examples... he always has an attitude and starts fights that eventually turn into me exploding because I've just had enough and that's the perfect time to blame the whole fight on me. Doesnt do shit but sit on his phone and smoke weed when hes at home, I have to ask for small things that couples do like, cuddle or get a kiss, spend time together without him on his phone. Most of the time those conversations turn to fights as well.hes just a mr know it all too and hates to be told facts he gets so angry and defensive.he pays absolutely no attention to me at all to the point I'm getting suspicious of him cheating and when I bring it up and try to talk about our future and our today he just goes nuts and gets super defensive again that hes not cheating and blah blah. I have tried to talk to him more times than I can count about issues we have and he doesnt want to hear it he just wants to fight about it .I'm over it at this point we cant even be grown ups and talk. Advice and input needed ladies ...
