Numb in this relationship.

Bf and I have been together for five years. we've been living together for a little over a year. we have a two year old son. our whole relationship has been his multiple lies, ignoring and neglecting my feelings, his porn addiction, keeping other women a secret from me, and I'm the dumbass women who went back to him. it gets a little better each time, but we should be way past this point by now. he's going out every night and is starting to tell me it doesn't matter what he's doing and who he's with. it really bothers me. my family was very dysfunctional and I could not live with them especially with a little boy. I don't know what to do at this point. he tells me I can't get a job because nobody can watch little one, and he tells me school is a waste of time. can't win for losing. I want to leave, but with no license and nowhere to go, I don't know where to begin.
