LGBT How do I know if this guy likes me?

[Oliver December]

He's pretty awesome. He's really sweet too.
I just don't know if he's trying hard to get, or actually doesn't like me back.
I know he is gay, it's all over facebook and tumblr, but here's an example,
when I talk about things, he involves himself in my conversations, which I don't mind AT ALL. he's a handsome boy. He's very very very very good looking, and I do have a thing for him.
So I gave my Tumblr, Twitter, and Facebook URLs to my friends and I gave one to him cause we were all having this small conversation and we all traded and stuff. So I followed him on twitter, and facebook, but he never texted me, or followed me on Tumblr or Twitter and idk. The other day he shouted my name as I got out of the car. that gave me butterflies.<3 ugh c: but I don't know! what do you think??? BLEHBLEHBLEH C:

If you don't know, we certainly don't know. Get to know him...

[idk]

ask him little by little..

Well, give him some time. Maybe he actually does like you and is trying to see how you are. You sound like a great person, he probably knows this. He might be trying to see if you'll get bored of him or maybe he hasn't gotten on Tumblr or Twitter or Facebook or even the internet.

You don't. At least not with the given information.

Dear God this is adorable. Sorry lol.
I think he likes you. My suggestion would just be make conversation with him as OFTEN as possible without being annoying. Every time you see him, say hi. Praise him without being obvious. If you like his shirt, tell him. If his hair looks particularly good, tell him. I LOVE when people do that; it's awesome haha.
And for the lack of my love of tits DON'T GIVE UP. This sounds so cute and if he really likes you it could be so f*cking amazing. Good luck!
