that is a tough one, i would think that it is just becuase of the son, but i dont know how bad it really is. does she like call him all the time or is it just when she needs something, if it is just when she needs something, she is using him and he isnt realizing it. does he pay her child support and have court ordered time to see the baby? if not he needs to do that, so when she calls becuase she needs diapers then he can ask what she blew the child support on. i think that it is just still fresh to have a new baby. but how long has it been since they havent been a thing? was it just a one night thing and she got preg? or were they *together* for a while?? there is alot of things that you have to look into. and if you have only been together for 4 months, i would think about this alot. becuase you dont really know him yet. i have been with my fh for almost 4 years and still dont know him, and we have loved together for 2 year. so.... you know i would think about it.
