You didn't say anything that you need to apologize for, and I am glad you are leaving her alone now.

When she comes home, whoever brings it up, all you have to say is that you don't approve of her continuing her new found chummy friendship with her ex. His inviting her to share his hotel room was totally disrespectful to her and to you.

Hopefully she will tell you she thinks he's an *** and doesn't want to talk to him again anyway.

If she protests, you know she is far from ready for real Committment. And I agree with Rose that if you look the other way and allow her to have this friendship with her ex, she will see you as being weak or uncaring.

Would she like it if you were spending the weekend with your ex?
