The good people here keep reminding me there is no room for a third party in a marriage. Stay strong.
Gordie- I absolutely agree. I thought I was doing the considerate thing by being ok with my husband remaining friends with her, despite my gut reaction to say no way! I didn't want to be selfish, but it totally bit me in the you know what. I feel a bit foolish now for not just standing up for what I believed in earlier. Better late than never though. Thanks for your words.
