Boy I like makes me compliments about my looks but says I'm not his type... Like what?

So I really like this guy but he said that I'm not his type, although he also said that we get along really well... He makes me laugh, he makes me smile and he makes me compliments about my looks 🙄 What can I do to make him understand that it's not the type that matters but the character? I already told him that I really like him (more than friends). I'm gonna be away for weeks/months and I really want to spend time with him when I return... But what if he finds somebody else? I'm confused and heartbroken
