sounds like he may be a tad bit jealous of you and maybe had his ego bruised.  Many men have an issue with women in their lives doing better than them financially.  They also like to see themselves as the caretaker to women.  They want to be the ones taking care of the family.  Im not including all men, but most.  He may just be jealous, and have a bit of a bruised ego with your independence.  If he was truely "in love" with you, he'd be happy for you and support you.  I'd question this man.  Ask him flat out if he feels insecure with you at this point.  But in my opinion, i think he already does and you need to think of you and your child first.  If a man cant be happy for you in a situation like that....then he's too selfish to be with you and your child anyway
