Should I stay with my partner or move on?

im currently with my partner of four years since moving in together two years ago with our two year old daughter. it started with trust issues theat led to us be violent to one another I stopped it all as I saw wat we were doing was totally wrong and geting us nowhere. but prior to this he has moved out several times to his mums its got to the point were is mum has told him hes got to stand on his own two feet
now were back together he constantly accuses me of sleeping around for instance if he invites a boy mate round wen they leave I get accused of things wat ive supposedly done with him. im not even allowed to sleep up my mum and dads house for one night. now he wants to grow weed plants in our home and I dont know wat to do? wat would you do especially with a lil girl ? and to top it off a new fella has come on the arisen and I dont know wat to do wat do you suggest?
the whole lifestyle is dragging me down and I feel my daughter and me deserve better

My advice, you do deserve alot better. 4 you and your daughter. He does need to stand on his own 2 feet. Let me tell you something: You ONLY liveONCE, make the best of it wile your here. Weed plants,0 really? umm.... well if he cant trust you, than sorry but hes not worth having. You dont have time to screw around, You have a Daughter!!!!!!!!!!!!!. I work with kids every day, little and big,disabled also and I put kid first before everything. There are next generation. have you done anything with him? just wondering,. not to be in your buisness or anything. He must have trust issues. If its a new trust worthing guy, and I mean trust worthing really!, then try it out, ( you never know until you try). BUT, make sure you can trust him first. wich relationship is better? GET to know the new guy, I guess dont tell the other guy idk about that, Are you in a marrage, If yes you needed to get to know him more. I advice would be sorry, LEAVE HIM, hes NO GOOD. DO what you need to do, you and your daughter life depend on it. Good Luck and God Bless You
