For once I agree with RedPepper. Your bf needs to tell his gf NOW that he has been having unprotected sex with you (and your husband) and may be the father of your child.
He is being very selfish and cowardly. All 4 of you, you, yr h, your bf and his gf need to be tested now, and so does anyone else your bf and gf have had sex with!
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
