S.O problems

Is anyone else's significant other completely absent during this process? My third Dr appointment and ultrasound is coming up- the third one he's going to miss. He was awful during our last pregnancy which resulted in a miscarriage and said how sorry he was and that he wanted to try again to start our family and now he's doing the same things all over again... I honestly would rather be a single mom at this point so I don't have to deal with him and his nasty attitude. Is anyone else in this same boat and thoughts?
