Help needed badly, I'm unsure

Hey everyone. I need some advice badly, so I hope you can help. This is it, so, basically there's this friend of mine who I've had a huuuge crush on... For years...We've been friends since, like, 2004, and he's a really great guy. After some time though, maybe a couple of years, I really started falling for him. He makes me so happy in ways unexplainable, I don't know why, I just feel really happy when being with him. I can talk with him about most anything, and we've been sharing thoughts with each other that we probably would never share with anyone.I have to leave out parts of the story, just in case, since I'm still in the closet for many, except a few friends (him excluded, he doesn't know), so I'm sorry to say that a huge detail is lacking in this story, but you can do guessing if you like, I'm just not gonna tell ;)The thing is, I haven't been seeing him for years, life just got in our ways, I guess, but again and again I keep thinking about him. I have even had multiple dreams with him in it. I've been trying to get over him and find others, and it worked for a while (though I didn't find any others), but the feelings he gave me just keeps coming back. I've been avoiding them for way too long by friend-zoning him, but I actually feel like I need to tell him in order to move on (one way or the other).Now, as it happens, life gave me another chance and I've already started talking with him again, and it's like we just clicked. We had long text-conversations trying to catch up with each other, and decided to meet.Problem is... I don't know if he feels the same way about me, or if he's even interested in guys, I suck at reading people unfortunately. Small clues come up though, such as sharing deep details at first contact, and when I told him that it was great to talk with him again, he replied with: "Very good to talk again indeed!". I don't know if it's just in my head, but last time we met physically (a couple of years ago), he seemed very happy around me, and was all goofy and gave me that stare, you know. Best thing is, I have a video clip of it, which makes me feel so warm and fuzzy everytime I watch it embarrased smiley here.But is it real or just me? What should I do next?, Tell him how much he means to me?, Or maybe just tell him I'm bi (leaning quite a bit towards gay) and see how he reacts? Maybe I should just try doing something as crazy as kissing him on the cheek!? Wait and see if he does anything? Leave clues for him, e.g. buying him stuff he likes?Help! This is the first time I've ever felt like this, and I'm just so scared of destoying the friendship we have :( I don't know why but I'm about to burst into tears of anxiety. What will happen, what should I do, What if he reads this post and realizes it's him?
