I hope she realizes how lucky she is to have a husband who cares about her so deeply. Finding this thread should eliminate any question about that. You are passionate about saving your M. You are committed to being a better husband, provider, and lover. You want a thriving, vibrant, passionate M. Maybe the two of you can work together on that, now that it is all in the open that you want it too.
I suggest you BOTH read 5 Love Languages. You love each other, but you aren't feeling loved. Something is getting lost in translation. Every couple should read that book.
