Should I allow my boyfriends children's rudeness, lies and theft from my children to break us up? His 14 year old daughter steals my 13 year olds daughters things and when confronted always has an excuse which gets her out of trouble. They are best friends and it is hurting my daughter. He says he loves me but never handles the situation to the benefit of all. I am at the end of my tether. HIs son calls me stupid when his dad is not around and then denies it when confronted. What am I to do? PLease help me.

I would say that you should break up with him if he can not handle his kids and they defy you. Your kids will end up resenting you as well as feeling like 'they can do it, so I might as well too." You are only headed for a totally dysfunctional relationship all the way around.
