The whole first trimester, my husband drove me nuts. Didn't matter what he did, we almost separated because it was so bad. But now we are getting better, he doesn't bug me as much. It's mostly all hormonal. Everything will be fine :)
Don't want to be snuggled*
That's completely normal. Throughout your entire pregnancy your libido is going to spike and drop dramatically. There are going to be some times when being touched in any way is going to make you want to scream. I would suggest looking online for some articles about it and reading them together. That way you both know more about it and he can be better prepared and not get his feelings hurt so bad when you want to be snuggled. There is nothing wrong with either of you, it's just the change in hormones and body chemistry. No worries. :)
Try thinking about when you first met and made love, think about the passionate times you spent together and when he kiss you ,you can stand it more.
