Hey peoplee (: lol so I'm 14 and I've been really confused about things lately with guys. im going to tell you about 2 guys that im really confused about.

I'm just going to explain some of the problems, sorry if its long..
Okay so I've always been the type of girl who is really shy and it takes time for me to open up and be myself in front of you, so I've known this guy for a little over 2 years now, we have been hanging out alot this year, we have wen't to universal like 5 times this year and he just came over my house a slept over like last week because we wen't to universal and we were going to be home late so it would just be easier if he slept over. we had like sooo fun together, but what gets me confused is he wont really text me anymore and at school he wont really say hi or anything I'll just see him looking at me, but its not lke he doesn't mention me though to the poeple he hangs out with because I heard him talking about me (not in a bad way) just talking about universal with me and going to my house last week.
I am like so confused... :/ I don't understand why we can't just be normal around eachother at school like we are when we hang out. it makes no sence.
And thats the first guy that im confused about now i'm going to tell you about another one.
So I've seen this guy around school, to me hes like one of the hottest ones there (: so anyways, he asked to be my friend on facebook yesterday. I didn't even know this guy knows I exist. haha so I was like really happy when I saw that he asked to be my friend. I think he knows who I am because we hang out with like the same group of people at school, he hangs out with the first guy I was telling you about also (: anyways, I seen him at school today and I just kinda catch him looking at me and kinda giving a nervous smile then turning around.
I'm so shy to talk to him..lol and i'm guessing he mite be a little shy too??
I need help! lol I am so confused..what are they thinking about? and just so you know, not being
stuck up or anything but I'm really pretty, you know like i'm not one of the shy ugly girls. im the shy "pretty" girl I guess you would say.
Anyways someone please give me some advice on what to do! thanks to everyone who helps <3
(:
P.S The 2nd guy has a girlfriend at the moment.
Alot of the guys at school act like this to me. I don't really understand..
They are both 14 like me.
