There is also the issue of him possibly being physical with another person - I am not sure what kind of details he wants about that shared here as far as what kind of arrangement it is, so I will leave that up to him to share.
The problem there is he wants to call that off as he thinks restricting me and not himself is hypocritical. I'm actually excited for him to have that experience as maybe it will help him to understand that it won't change OUR relationship. But it's not entirely the same. Like I said, I'll hope he comments here with that info.
