Well LonM. You are just the teaser bull. Just there to keep her all warmed up and ready for the next " real" thing. IF you where the right man for her she would know it now and not be looking at other men.
DUMP her right now. A good friend of mine has wasted the last twenty-five years on a woman just like this one. She had a little girl that was just a few years old (father was a bad boy that ran when she got preggers) and he fell in love with the whole family package. He married her. She was alright with it for about six months to a year. She then kicked him to the curb for the next "BAD" boy she got hot for. My friend actually paid her support for the little girl just to be able to get to see the little girl. So lets fast forward. The woman goes through 6-7 more men. Another "bad" boy gets her pregnant again. She has another little girl. My friend starts to take both girls every other weekend. The woman then finds her next sugar Daddy. she marries this guy and moves a 600 miles away, has another daughter. My friend, the sucker, moves so he can see the kids. She gets divorced and she all of a sudden wants my friend back. The DUMB butt remarries her. It lasts two years until the next door neighbor/bad boy gets her motor running again.
She finally admits to my friend that his only attraction for her is that he is mister regular guy that always can be counted on to provide for her. She really is not attracted to him but what he can provide her.
So here is the grand sum of him and her. He is 55 years old. No biological kids of his own. Last of his family's name too. He is past the age that he wants to have any new kids. So he has three step daughters that he loves but nothing else after fooling with this woman for 25 years. Now that her looks are starting to fail she is trying to get him back again but he finally has seen the light and just laughs at her actions now.
This could be you real easy if you keep valuing yourself so low that you put up with her crap. Have more self respect than to let her walk all over you. Dumper her and move on.
