I Want to Be In a Healthy Loving Relationship

We usually tell ppl to leave an abusive relationship, however we need to tell them how to do so. I'm afriad to leave mine as im afraid my child grows up wo a father figure, I am holding on to hope that my bf will change, Im afraid I'll be cutting off a group of ppl that love my child. However he don't sleep w me, we don't communicate even when were on good terms and he has a lot of support from his friends.
