You say you've had other loves before. Did you husband know about those, or did you keep it on the downlow? Was your new affaire de ceour a complete surprise to him, or part of a pattern?
It's interesting your h is up and down, considering maybe staying with you and accepting you being poly. This is normal. It can take many months, even a year or two, for a previously mono couple to open up.
Maybe he will come around. Make sure he reads Opening Up.
Meanwhile, my usual reaction to someone being knocked up at an extremely inconvenient time is, abortion is legal. Very bad situation to bring a new baby into!
Does your h know you've had unprotected sex with new guy? Everyone needs now to be tested for STDs. Does he know you might be pg or are you waiting for until you take a test?
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
