I've dated my BF for over 1.5 years, still trying to figure out if I should run for the hills.  Anyways,  he has a 6 y/o SS, and the child isnt awful or mean, but everything the kid does irks me. As a quick backstory, 
My BF has had problems with BM,
BM would completely ditch the son leaving BF as primary parent. BM would not call child, didn't care about child at all.
