I have been married for 20 yrs, my husband hooked up his X with our best friend. I get along with her well enough now but in the past it was very rocky. I do not want her in our circle of friends and will not have them over for a dinner party. She has in the past approached my husband and was looking for a one more time for old times sake....He said no. Two weeks ago the three of them went 4 wheelin while I was at work, and last night he went to the bar with them while I was at work. I stopped in on the way home and hubby said he would be home shortly and that turned out to be 4 hours later. He says he doesn't care if she dates our friend so why should I...Bfriend helped us build our new home and now wants to give X a tour?? I have a problem with this am I being insecure or is hubby being a brick head??
