My ex husband and I have 2 kids(13,10). We are both remarried with kids from new spouses. My 13 yr old is a TROUBLED/DANGEROUS child who likes to tell lies and cause a lot of problems for everyone. I had enough and told his dad he can not come back to my house until he gets help. I just found out he has ADHD/BIPOLAR/TERETS. My husband says he is not allowed back for the safety of our 2yr old and newborn. What are my options of not letting him come back?
