I agree with the first two posts (they are the only posts there so far as I write this, so I might agree with any others that are being written while I write mine!).
You go through so much so you two can have babies (pregnancy is a lot to go through!), and he disrespects you by not giving you the love that he should. That is so bizarre, and it's incredibly hurtful! I would be SO hurt if I were you.
The question DEFINITELY is: What is wrong with HIM?!
If my husband did this to me, I would highly suspect an affair. He's a GUY. They have very strong desires when it comes to intimacy. If he's not getting it from you, where is he getting it from? I'm not trying to stress or scare you, but that makes no sense to me on any level. You're around the 7 year mark for your relationship, and some people get the "7 year itch". I would definitely investigate that and find out if he's being faithful. And, there is no man or woman on this earth (in my opinion) that is 100% trustworthy. If they are showing weird signs, something weird is probably going on. And, your hubby is showing weird signs.
Just to give you an example of what I think is more typical, after I have my babies, my hubby can't wait to be intimate with me again. He's not pushy with it, but it's something important to us both. It doesn't matter if I still have 10-15 lbs on me, he isn't less interested. He doesn't seem to notice, but I know he does because he'll mention how I'm trimming up once the weight starts coming off. But he never loves me less when I still have that weight on me. It never affects his affection for me. He thanks me regularly for having our babies and never seems bothered by anything it has done to my body (due to have baby #5 soon, and it's definitely messed with my belly skin and muscles!). But he still looks at me like I'm the most beautiful thing in the world.
That is what I consider a normal man. What your husband is doing is not right. Even if he isn't having an affair, it just makes NO sense at all. If he truly loves and cares for you, how can he not be interested in you?
I would definitely push the counseling thing. It doesn't matter if he thinks there isn't a problem. YOU think there is a problem, and that should automatically mean there is a problem.
I hope you find out I'm completely wrong and your hubby is 100% faithful to you. But the problem definitely is NOT with you. It shouldn't really matter what happens to your body (well, maybe unless you gain 100 lbs...then I could see some concern on your hubby's part, but it shouldn't lessen his love). Your hubby should be there for you and love you as a husband loves his wife.
I'm so very sorry you are dealing with this. I'm not sure there's much else that could hurt you so much than to feel rejected by your husband, especially when men are so opposite than that.
