Thank you for your fast reply and bluntness Mono.
I definitely don't want to demean her value of marriage. There are a lot of things that I value about marriage too. What I would like is more acceptance loving other people in an intimate way.
No, I'm not interested in this new relationship just for sex. We have a more spiritual and purpose aligned connection than anything. The physical connection is nice, don't get me wrong, but that is not my main reason. I didn't even allow myself to have these feelings for her until she expressed them to me.
