What makes a man blow hot and cold?

Like, you’re friends and one minute he’s all affectionate; the next he’s denying having flirted with you, then talking a lot, then making excuses not to go out, like a fear of intimacy, not being sure what they want, or there being no point in dating? Wasn’t it interesting that after you’re losing thirteen kilos, the same guy returned with an entirely different story, about how interested he’s always been in you? When you’ve become almost as attractive as he has but didn’t start off that way?

Do men get embarrassed about/ grossed out by fat, plain women? Was that what caused the ‘fear of intimacy?’ I’m not complaining, just thinking out loud. In writing.
