This happens more often than not. It's an adjustment. A HUGE adjustment. He might be jealous because all of your attention isn't on him like it was when you were pregnant. It's all about the baby and some men have a hard time getting use to that. Honestly, it's just something he's gonna have to get over. Pregnancy of the first child is usually the honeymoon period. Granted this is an exception to many couples but in your case, this is what is sounds like.
