Emily, I keep remembering the photo of your black eye H gave you. Please tell me there's no violence currently - even if OW were not pregnant (GAWD, how awful!), H would need some serious counseling for the anger and avoidance of issues he has ANYWAY. You 2 are not an island and your R will be no different w/out some SERIOUS changes and you have to have some intervention here for that to be permanent. JMO, obviously.
