I dated a guy who was much larger than what I would consider "average," as he put on his profile. He gained more weight after we started dating, but he had some redeeming qualities I admired. In the end, it was a disaster, and not just because of his weight. See my story if you are wondering what I did. I don't usually include a link in my comments, but for this one, there's no other way to explain it. The bottom line is that if he lies about his height and weight, he will lie about other things, too.
