my ds has just turned 11 and has been brought up by my (now)husband since he was 3 months old. he doesnt know that my dh isnt his biological father. it wasnt a premeditated decision not to tell him. he has had behavoural problems since he was young and doesnt cope with change of anytype of conflict and we were just trying to work on that. but know it has gone on so long i just dont know what to do. i feel he has a right to know but have made a really big mistake in not telling him before and now dont know what to do. His biological dad isnt interested and has only seen him once when he was 1 week old. any advice or experience of this will be gratefully received
