Hi Happy,
My ex-husband did something very similar to your husband...except my ex was meeting women and having sex. Reason # 1 he's the ex-husband.
If your husband has already taken this step to look outside of your marriage for fulfillment its over. I'm sorry.
I'd tell him within 30 days he needs to be out and if he's not....Kick his butt out of the house and change the locks. Then make an appointment with your doctor and get tested for STD's.
I'd also put a fraud alert on your credit report so that he is unable to take out anymore credit with your name attatched. Please protect yourself.
My ex-husband took out an AMEX and Discover in my name 2 years after we had been divorced.
On a happy note, I have a really wonderful husband and 2 lovely little boys and even with all of my husbands JW issues, I'd still put up with it anyday over my ex's cheating and lies.
Be careful!
Chrystal
