Reply to Is it okay to take a break from our marriage

So just as a short follow up she has settled on wanting to date other people. She says she is going to go experience a sexual relationship with this other man, and that after that we will see how she feels. I am not sure how I feel about this. Honestly, If she had come to me before I discovered the relationship on my own I would have been okay with her starting this idea of an open marriage type situation. I’m still not sure how I feel about this.
