Hmmmm, intersting thread. Lots of good posts here, lots of good advise.
BUT, you seem to be forgetting a few things.
Number one: What about love??? His ex-wife may be the one true love of his life. Remember "it's in the kiss" from other posts on this forum. If he didn't have it with you, and does with his ex, you'll never be able to overcome that. Thus, walk away. However, if he has it with you and doesn't with his ex, he'll need some time. Took me from Sept to Jan to realize it.
Number two: You'll always be interested when someone pushes you away. If his ex found out he was dating you that is proof positive to her that he is indeed pushing her away. Thus, she will want him again. That usually happens a couple of times until both parties see through it. Conversly if you pull someone toward you (chase them) they will tend to go the other way.
Number three: Any kids with the ex??? That's a big one. If so, walk away now because you'll have to deal with his ex the rest of your life.
The comments on the sex are simply wrong. Of course I'm a bit older now but even as a kid I was looking for intmacy - not sex. Sex may allow you to forget your past and help you carry on a little easier but it DOESN'T make you forget about real love. "It's in the kiss" type love.
That women use sex to entrap men is a problem also. It's not always the other way around. Matter of fact, the experiences in my life say it's the women that are so casual with the sex. Seems like they can switch partners without much thought or consequences at all. Like buying a new outfit or changing their hair color. Just doesn't matter to them. It's only sex type attitude.
One other thing is after a while men get almost scared of women. Get nervous around them. They honestly don't know what to do to make them happy. It's not like running a business where all you have to do is have a great product and love your customers. You know, be nice to folks, genuinely serve them, have fun with people and get the job done. That doesn't work with women.
You make us feel like we're nothing more than just another possession. Just something else you have to deal with. We're such a problem for you. Well, we don't like being problems, we like solving problems.
I can guarantee you this guy is very confused right now. If he does have "it" with his ex he'll find out. If he doesn't have "it" with his ex he'll find that out too. But chances are he has had enough of women for a while and just wants to be left alone.
The women in my life have taught me the following.
In general men are good for two things.
1. Good for nothing.
2. No good.
We try, we really do, but we always fail when it comes to you women. If we're nice to you - we're whimps. If we are not nice to you - we're abusive. Can't win, and after a while we don't want to play the game anymore. Peace becomes more important than anything else. And that's probably all this guy is looking for.
