Is it normal that i think i'm in love with someone that's paid attention to me?

For someone that hasn't even experienced puppy love, yes it is. Have you considered lowering your standards? I'm sure there is a lonely guy that's out there just waiting for his presence to be graced by a girl as lovely as you!

This is called, "being 19". It's totally normal :]

I don't know if it is normal but I am the same. Personally I do not think it is lame, delusional yes, but not lame. I empathize with you. Whenever a girl talks to me or expresses that she wants to talk to me I become convinced that she may be infatuated with me; however, I know that I am wrong. Thus, I suppress the feeling and convince myself that she just wants to have a talk because we are friends. Due to my suppression, I can sort of control my infatuating but my delusion is still there.

You're not "LAME," you're just inexperienced. There is nothing wrong with that. Most men would be understanding of that, and some would even find your innocence/inexperience attractive.

ask them out!

Waiting for a guy to ask you is EXTREMELY archaic!

Same thing happens to me. I feel so conceited for thinking it though.
In my head I'm always like, "Ladies, please. I have a girlfriend you know." :p

Even for people who have been married and experienced all kinds of love, someone paying attention can be distracting. It's well-known, for instance, for patients to fall for their psychiatrists or doctors because both professions and taking notice of them and want the "patient" to feel better.

If someone pays attention to us, our first question should always be what their motives are, rather than how it makes us feel.

no, it's normal, it's just infatuation and it's normal, you just need to talk to more people and you will find the right one, someday :)

As a lady no matter how you look you have the upper hand when it comes to hooking up with people. And since you are so young chances are you first couple of boyfriends are going to be just hooks up like some one to hang out with or something like that. Trust me you dont not want to be in a serious relation ship until you are 65 or 70 its not worth the headaches and pain and grey hair. Stay single until you die thats my motto just wish i had of listened to myself.

I have a friend that's exactly like u!!! like in class...there's this guy...[who thinks he's a lady's man, but he's not] and so he make say a joke to the whole class and just laugh2 the person nxt 2 him...so when he did that my friend was the person he looked at and laughed...and then class was over....so, after class she just came up to me and said, i like nick!!! and...not to be rude, but she kinda dumb, cuz i had to remind her that she already has a boyfrend...but all im sayin is if u get a bf, but some guy says can i borrow a pencil, dont just be like omg hes soo into me!!!

Wanna marry me?

Lol yeah that's pretty normal. But don't worry I'm sure youl find someone who loves you for who you are. I think that your the shy type of girl and that's something precouis that many girls these days have. And many guys will find that very attractive. Ooo and a other small tip is that t wouldn't hurt to put yourself a little out there.
