Sounds like you are doing great and just need more time. 2 months is nothing. Especially after 1 year of doing everything wrong. YMMV but I would expect at least 1 year of DB'ing before you begin to approach "normal" again.
Mom's disease can really turn a guy off but it sounds like you are addressing that. Good you've changed your undergarments and slyly let him see. Try losing the undergarments and slyly let him see that. Again, YMMV but sometimes catching a fish is about having the right bait.
