I remember the dark days with my ex. Once every 4, 6 or 8 weeks. Aghhh. I never want to go there again. I thought 2 a week was normal/ok. I have dated some women in the past that daily was fine. LOL. Funny I'm HD in one R and LD in another. Go figure.
Your H has made some good progress. I'm impressed. As long as the baby steps continue, you guys shouls be fine.
