He's giving me mixed signals, please help!

So there's a guy I like, we're friends for 3 years now. At first we were so close, we were talking everyday for hours without getting bored, we were having so much fun. Although we're still close, but we don't talk much like before, and I'm always the one who starts the conversation! sometimes I feel I might be bothering him :/ I told him he'd changed he said he's like that with everyone. Sometimes he ignores me like he doesn't know me at all! one day he walked past me looking directly into my eyes without saying hi or anything! and one other day we were standing together (talking), I was looking at the floor and there was a strange guy standing in front of us staring at me, he got angry and said "what are you looking at?" like he was jealous or something, I said to myself maybe he does those stuff around all his female friends, but he always stares at me ,well it may be weird but no other boy looks at me that way, I mean I can see love in his eyes! we were talking about marriage once, he said "if I ask you to marry me, would you say yes?" he sometimes talk about those stuff and then say he was joking, well, I do the same.. By the way he's one year younger than me :( (technically 7 months) but does it matter? I've never thought I'd like someone younger than me and specially him, but I did! so I really need help in this! Could it be the only reason he doesn't want us to get together?

7 months is absolutely nothing. If that's what you're worrying about then stop. My mum and dad have 7 years between them so do not worry. Just ask him out! and as you said, you and him always joke about that stuff so if he says no, then say you were joking. Try not to do it with his and you're friends around because it may actually look like a joke, you don't want that if you're asking him out seriously. Just say it was a joke or a dare. Good luck. :)

7 STUPID MONTHS? IF THAT IS WHY GOOD LORD HE HAS PROBLEMS!! ok it seems like he likes you but cannot express it so maybe you should make the first move or say like "If I all of the sudden kissed you, would you kiss me back?" and see what he says or if he goes red

OMG I can relate forever on this question cause I have this guy friend and he is doing the same thing! But instead of 7 months apart were 2 days! And he won't even look at me when I'm looking at him anymore :( honey 7 months is fine and at least you two talk at school he totally ignores me !!! :'(
