Is my guy friend gay? I like him?

Pleeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeee… Do me a favour, and don't let him pass through your fingers. I made this mistake and I am 25 and I have regretted it ever since I was 16. Please! Please! Don't let this opportunity pass as you will regret it. If you haven't come out yet, please be true to yourself. I am asking you, and you deserve happiness. I can't emphasise how important this is.
