Wow, I'd break up with him RIGHT NOW, before your pregnancy starts to show.
Even before you mentioned his self diagnosis of BPD, I was thinking his behavior reminds me of my adult daughter, who has medically diagnosed BPD. The erratic impulsive behavior, food issues (she's bulemic), the rages, sexual inappropriateness, the overuse of alcohol, etc.
If you're afraid he'd take a gun and shoot you, please cut off all contact with him right now.
Love withers under constraint; its very essence is liberty. It is compatible neither with envy, jealousy or fear. It is there most pure, perfect and unlimited when its votaries live in confidence, equality and unreserve. -- Shelley
