Hi, i need your advice and thoughts here. My OH and i live apart. We have a DS. When OH comes to see us he behaves like we are in a normal relationship, physical and emotional. Sends texts, rings, i love you etc. He has been withdrawn with us both for a couple of weeks, tonight i find a post on facebook and he has sent OW flowers. He doesnt pay a penny towards DS and never has. What do i do now???
