Hi Navigating, Well your post did not ask for opinions, but what the hell. I found your post pretty interesting. And basically verified some information for me.
When I look at open marriage, my first thought is like you said, why get married. I have heard that as you pointed out it is just about sex and has nothing to do with love or your feelings for your spouse. All a contradiction to me! If I was married and wanted to have sex with someone else it would be because I had lost love or respect or both for my husband.
You may be sorry you did not marry Steve, but I don't think so! I think it would have been difficult for you to live with.
This new man you married so he could live here legally!!!! Sorry Crock! You sound like a nice "Jewish Girl" LOL, with a good sense of humor. (my opinion after reading your post) Anyway, what are you doing wasting your money and your time and your everything. And NO SEX! Excuse the pun but screw him. You are living life alone basically anyway. Get a pet if you are lonely. You don't need him or anyone else to have a good life! And don't settle!!!!! You can not live your dreams if you do!!! Good Luck
