8 months pregnant and dealing with bipolar ex, advice?

Okay, I understand. You may still love him and he may be intelligent but as if right now, he is whack! Don't call your baby's daddy until he has had help. Think about, you don't want an abusive alcoholic near your baby and risk it's life. If you want the best for your child, I suggest you one, find a new helpful and supportive man and call your ex after a period of time; or two, wait a few years until your ex fully seeks help. Until then, I wish you the best and good luck. Your child's life all depends on your choice. ~
