My boyfriend and I have been living together for almost 2 years. I have 2 bio kids aged 6 1/2 and 4. He has 2 boys aged 6 1/2 and 11. My oldest and his youngest are 6 days apart in age. A few months ago his youngest son's BM decided that she only wanted to see him every other weekend and for him to live with us basically full time. He has always been a handful but since he moved in with us full time he's become horrible. He hits my kids, screams at me and never listens. I dread mornings when he wakes up and afternoons when he comes home from school. Just being around him makes me angry. Recently I caught him touching my daughter's behind inappropriately and my boyfriend doesn't seem to think there's anything wrong with his behaviour. I'm so close to leaving but I don't want to drag my kids through it. They're not perfect children, I can admit that but they are much better behaved than his son. I'm running out of options. We've tried having him talk to a social worker, we've talked to his school to find programs for his anger issues but nothing works. Help!!
