Becca,
It sounds like to me your husband does indeed love you. But it sounds like he has problems handleing stress like most of us, mixed with poor communication skills. If he were better able to communicate his stress and feelings with you I'm sure you would have a much easier time having faith in his love.
I'd feel hurt if I was talked to in that manner as well, and I have been.

. I'm sorry your dealing with this. Remember that he might not know how to communicate efficiently and that is nothing personal or to do with you. I don't know how open your husband is to things like therapy or self help but perhaps he could read a book on the subject or something. I have no idea how to get men interested in this kind of stuff tho.
