How long have you been with your 2 men?
Your bf has a learning curve about keeping busy when his poly gf is with another. Jealousy is a horrible feeling! If he's only been with you a few months he is in NRE and that can make you driven to spend as much time as possible with the new lover.
It's on him to distract himself that ONE night a week he can't be with you! LOL. See friends, work out, get a new hobby, anything intense enough to be a solid distraction. Compersion can grow out of jealousy but it can take time. I hope he doesnt feel in competition with your husband and make any cowboy moves to get you all to himself!
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
