There could be many reasons for your husband to feel the way he does. The top 2 that I could think of is:
1- He's not attracted to you for some reason. Maybe you're not as you were when you got married (ie: weight, hair , wardrobe, etc). or
2- He's cheating.
I know what it's like to deal with an irrational person who when trying to communicate to solve problems, it seems to be nothing but a hassel and all you do is argue. Have you asked him if he's been unfaithful? (I bet that started a fight) Has anything been a little off with him? If so, you have every right to check his cell phone, pockets, even follow him. It may seem wrong or you may feel bad but you're his wife and you have a right. There's no such thing as privacy when you're married unless you set the rules that way. If you wouldn't have a problem if he did that to you, then you have nothing to feel bad about.I once waisted 2 years in a relationship b/c I thought it was wrong to follow up on suspision. Once I did and I was right, I was kicking myself b/c I wish I would've done it sooner. The fact that he wants you to return to work actually ties in both conepts. He either wants you to "occupy" yourself so he can do his thing or He want you to get back in to the swing of things so you can become more like yourself before the baby.I hope I'm not scaring you but like I said, the sooner you rule the worst, the better you'll feel, and the sooner to finding out what is up with him. I wish you all the best. I relly do.
