Not every woman would put up with this for as long as you already have. Ask yourself why. It's not just because you love him. At some level, you are holding on to him out of insecurity. Also you tend to see your worth as a "good" person to be all tied up with how willing you are to be giving. That's kind of materialistic when you think about it.

It's okay to choose to love him AND to leave him. The heart and brain do not have to always be on the same page. It does take experience with life to see that. This is why so many women stay in bad relationships for so long before they leave. It's not that the guy necessarily becomes any worse, but the woman becomes more mature. That makes a woman less vulnerable to being exploited. It is hard to face that a guy you believed chose you out of love was really most attracted to your innocence and vulnerability.

What other relationships has this guy had . . . and how did they go? Look past the self-serving version he related to you about each failure at love. He probably had a few false starts with women who refused to be taken to the cleaners.
