Another worthy article of note:

Thank Psychology Today

"You are not valuing your own self enough to make yourself a full partner to a relationship. That failure to validate yourself is going to undermine any choice you ever make. If you respected yourself more, you would be able to exercise your own judgment—and see that you've limited your possibilities to two men with serious flaws for a relationship. It's almost impossible to build a joint future—the purpose of marriage—with someone who has different views of life than you do, unless you talk those views out thoroughly and can make them mesh in very specific ways."

And from another article, for any women out there who have sat in a relationship or marriage for a long time before deciding to leave:

"The letters make it clear that the women fall for the guys quickly, then spend a long time in struggles to transform their mate before coming to rue their choice of partner."
