Welcome Peekablue! (What a cute name! I hope it changes soon though and you feel better)...
I think you should see a sex therapist on your own and if/when the time comes when the therapist wants to see your H and/or you want him to come to a session... that will work best.
I started seeing a therapist on my own and we just started seeing her as a couple...
It's wonderful to hear from an LD wife sporting such a great attitude! Give yourself a huge pat on the back for doing something about this and not letting it go. BRAVO!
Have you read the Sex Starved Marriage yet? Has he?
