I don't think I have said this yet but congrats on the baby! Sorry to hear you are starting to feel uncomfortable.
It sounds like a year in rehab is a blessing, hopefully he takes this wonderful opportunity to get himself clean. It will also give you a break to enjoy your new little one and to only worry about yourself and your baby. I always feel the best when my AH is in rehab as silly as that sounds.
I will be praying for you,
Daisy
