He settled for me?

My husband told someone that he settled for me and that I don't make him happy, just content and that he would just pretend the missing parts till he felt them. That and I quote "I'll take what I can get". It was a few months before he asked me to marry him. I don't know what to do. I feel like I should confront him but the person who told me is the one he told and she asked me to not say it was her. I feel so lied to and betrayed, I haven't cried like this since high school. She was his first everything and I don't know if he said those things in hopes she'd take him back or even if he really ment them or if he still feels that way now but I can't help feeling like he's lying every time he says he loves me or says I make him happy. I need some guidance or support or someone to tell me I'm wrong and that the fact he married me should be enough proof of his love. I've loved him for five years, I can't stand the thought of loosing him but I can't keep him if he doesn't really love me.
