Just learned that my new husband has been emailing with old Girlfriend on facebook.?

He's talking about you to another women - that is NEVER good
who knows what has been going on in those conversations or with them. Yes you are nuts to stay with someone who is keeping stuff like that secret. Most people do talk to their exes I will admit that but they shouldnt keep anything from their current spouse about ANYTHING.
If you feel he is not that into you you need to stand up for yourself and let him know that you find it uncomfortable and need it to stop.
If your still unhappy leave - I am sure you can find someone to respect you
