Cheating boyfriend (Daughters father)

We were involved in a relationship since December 2007 & In September 2008 i fell pregnant We now have a 3 year old daughter.My problem is that my boyfriend started cheating on me sometime in 2010 & in October 2011 one of his girlfriends called me & insulted me on my cell,i ignored it & thought it was a wrong number & soon after that he stopped making love to me & always told me that he is tired,or if he knows that i am home he would go out with his friends come back drunk & just fall asleep.If i am not home ,he calls me to come & visits him when i go there he lives me @ home with his mother & go drink with his friends.I confronted him about it & he says i am the one with the problem.He says he is not cheating,he needs his space,he is not even talking to me,he stopped supporting his child.What do i do? do i wait for him untill he comes back? do i move on? I am hurting very badly.Confused mother in Pretoria
