You are not a failure as a husband! This is one of those situations in which I wish I could show someone what they look like through my eyes. I know that I don't know you in real life, but from what I've read, the vibes that I feel, that there is just something very good, true, and authentic about you. You're a good husband who strives to be better every day, and you think about these things. You care, and you've been trying to get that across to your wife in your marriage. You can only do so much at a time. Be patient with yourself, if you can be. You still have to take care of YOU. (hugs)
