How to deal with fiancée having fun in Vegas?
My fiancée is going to Vegas for the second time, about a year from when she went last time. She went to Vegas last year and ended up exchanging numbers with a guy there and became infatuated with him. They texted for a few weeks and I found out (from a text to her friend there with her) that she had strong feelings for the guy. We had a long discussion and she realized she f'd up and made a mistake. She is going back for her sister's bachelorette party tonight and is planning on doing much of the same. (i.e. pool party, clubbing, etc).
She told me before she left that I have nothing to worry about, she promised to be a good fiancée. When she went last time, we were not engaged.
I want so badly to trust her, she has done nothing to prove otherwise since. I guess I am just having trouble getting over past issues. I guess I should just let her have fun (first instinct) and trust her, but it is so hard to do. I heard from a couple married 30+ years that is you can't trust someone on a trip like this, you should just take back to ring. I love this girl, what are some good ways to just not worry and let her have fun (within reason). Please advise.
