Nothing - he has moved on and you must too.
no she still has a boyfriend
He is married. You are done. Block his calls and emails and move on. No good can come of this for you.
Leave him. He does not plan on getting a divorce and being with you and you only.
he might still have feelings for her.
I am pretty sure she is not. She is supposed to still be with her Boyfriend.
I think you should talk to your boyfriend and ask what he thinks, even if it is just a text message or an email. I would take it as a break up.
You probably can, but I don't think you should jump into anything that quickly.
All accounts state they were still happily married six months after the show finished taping.
If your ex does not have a boyfriend or is not married and only dating then phone her (don't text her) and ask her if she will meet you somewhere and then discuss how you feel about her.
you should move on
Your husband can sue you and your boyfriend depending on your states laws. Also, if your husband finds out you are dating, a judge can grant him a divorce on the grounds of adultery.
If you and your boyfriend are still dating and have not split up then this friend of yours is not a true friend to you and you should consider her a toxic friend and walk away from her. If you and your boyfriend broke up and she dated him and obviously didn't tell you it is probably because she didn't want to hurt you. In this case talk with her and tell her that she should have been honest with you, but you should still remain friends.
