Am I wrong

Am i wrong for being crazy. So u have a boyfriend were 11 months to this relationship and it's not healthy  at all so it all stated one day I was at work and he did drugs behind my back and then afte that he cheated on me and then  after that there was no trust I thought we can fix our Problems but  I guessed wrong it's been problem after prom elm and the bad thing is I live with him my mom passed away. And  dod got remarried  and kicked me out so only person I have is him I sometimes feel trapped but I can't always have this feeling he has done so much stuff to me but I can't live this Life anymore
