Ruggedendurance,
I love nice guys and always have. I just seemed to pick really screwed up men with FOO issues. This is your W's MLC. It sounds like you are a great husband. Own that. I can honestly say I do not like overly macho men. They tend to lack the ability to be romantic, emotionally intimate, and nurturing. I doubt H and I will ever get back together, so all I can say is the next man MUST have certain qualities that are deal breakers. I will not settle for anything less.
I made a long list of everything I wanted and needed in a partner and here are some of those qualities: ability to embrace and show emotional intimacy, be 100% honest, romantic, friendly and pleasant, respectful, selfless, faithful, intelligent (or at least have the ability to hold an intelligent conversation), take care of his body (doesn't have to be a body builder, but at least try to be in shape and eat right), finds me desirable (my H withheld compliments, love, affection, sex for 2 years pre-BD), embraces and accepts my children, likes animals, spiritual, and willing to work on relationship issues (H did not believe in therapy, discussing marital problems, or utilizing our spiritual program).
H meets maybe 2 of these qualities. He's so far away from my list of an ideal partner I no longer find him appealing. Everyone's partner list is different. Have you thought of qualities you want and need in a partner? Would your W still have the qualities you desire on that list? Make the list without thinking of her.
