OK. Um, wow. This may be the first time I tell someone you need to get away from this person. With all that's gone on between my wife and I we have never talked to each other like that. Telling your child you wish you never had them is right up there at the top of the list of worst things you can do to them. Physical abuse is also completely unacceptable.
You say he is on meds for bipolar? Did he start taking those recently in an effort to win you back or has he been taking them for some time and they do no good?
IMHO, you should not let him back into your house at this time. He's going to have to show you changes from a distance and that the changes stick.
With all that he's said and done to you and your kids, I'm scared for you. Do you fear him?
I hope someone else steps in here with a little more experience with this type of situation but from what you say this is the type of relationship that even Michele says you should get out of.
