Help me read this situation I'm at a lost cause. EMERGENCY!!! lol earn yourself 10 points this is easy :D?

OK this guy is basically obsessed with me and I know for certain he likes me. Only trouble is Im a guy and hes a guy. The thing is, whenever I mention the fact he likes me or hes gay he denies it but carries on the same with me. Everyone else has started to notice it and theyve been talking saying they think he gay too. But what do I do? Do I wait for him to come to terms with it or just confront him now? The thing is this has been going on now for two years and recently I lost a bit of weight and a lot of people keep commenting on how hot I am and his obsession and haring of me has got steadily worse. HELPPPPP lol
