FWIW - Just to tuck this into the back of your mind: You said your H totalled his car New Year's Eve. Concussions can be associated with subsequent depression, or even hormonal imbalances due to damage to the pituitary gland in the brain. I just wonder how much of this is MLC (entirely possible, as he is now rich and therefore attractive to the girls who wouldn't date him in high school) and how much is depression or other issues from the accident.
As for what you can do in the meantime - it's hard when you're pregnant, but DBing can be done. Think high road, think independence, think good grooming. Be the wonderful madonna, great mom, fascinating woman who has let go entirely - let HIM worry about whether he's blown it, and whether he'll be able to get his family back.
