I know this post is a half a year old, but I haven't really been around that much to thoroughly read the forum, as I left a couple of weeks before the original post was made. But, goodness, that's more than a wondering eye. I think that nearly everyone has sneaked a peak at someone, whether it was tangible or not. I know I have a slight thing for a professional wrestler I love, and it's not bad at all, especially considering there's no way I'd ever get my way to him. But when your partner is actually getting their way to people, I'd consider it a problem. Maybe I'm a bit old fashion, but there's no way anyone can ever claim to love someone and then want to sleep with others. To me, it doesn't make any sense. Being in love isn't about reaching out to others.
I haven't read the whole thread, so I don't know any updates, but best of luck to you.
