Glob,
I really wasn't much of a wife to my H in the early days of our M.

I can't speak for him but I don't think he thinks highly of himself, either.

It kinda took us hitting rock bottom...or, rather, getting to the point where there was nothing left for each other--only the fondness of shared memories and of course our children to get us to see that there HAD to be more than this.
Fwiw, I had to drag him kicking and screaming through this process in the beginning. Just cause your W doesn't want to do this doesn't mean that she won't come to love the idea.
There've been lots of ups and downs but we keep slogging through life because when it's all said and done, he's the one I've pledged my life to, and I want that life to be a good one.
