I am going to be a friend and give you a shot of "ball tonic".
I am not an uniquely HD or caring woman. If I were single and living in the state of Missouri, I would certainly go out with you, I would probably have sex with you if the chemistry was right (and it would probably be fantastic) and if I were involved in a long-term relationship with you I would try to be civil to your ex-wife and loving towards your children.
You are in a Win-Win situation. If you confront your W, either you will start having sex with your W or you will be able to find a woman who will have sex with you and meet your other basic requirements. The only thing that is keeping you in a Lose-Lose situation is the fact that you are a wimp.
