Is it normal to keep remembering someone?

It's been like two years ago since the girl I love at first left my life.

I'll begin...

She was kinda stalker, without me noticing she's been all time taking me photos and sharing them with her friends. Being the weirdo I'm and taking I'm mind no one else would care about someone like me, when she tried to talk to me through a friend of her, I obviously accepted.

It didn't took too much time for her to reveal me the fact that she was a stalker and the whole thing. That didn't sound crazy to me, I mean... Maths! Weirdo + weirdo = weirdos. So you get the point...

Great. At the beginning, everything was perfection. She was so perfect, lovely and comfortable. Also, I always thought she was feeling what she shown in her face. Here is when the problem comes... I was like fifteen and she was like thirteen. Age difference seemed to matter but I didn't notice, also, I accepted to be just friends and hold a limit of "only hugs", even while everyone else told me to kiss her.

You'd say: "it's just a kiss", but she didn't want to and I was gonna respect it. I really feel like I gave everything for her and I feel hurt cause it took almost three months for her to get to date her "best friend?" when she told me nothing was going on with that guy; they were kissing and someone told me they've even had sex then...

It bothers me so much! I mean... Do you imagine how much were my expectations? Being the first girl I try to date and she was so lovely, cute, smart and mature; even being younger than me!

The worst part is how we ended up everything. It happened all in a message. She just told me from one day to another: "I don't wanna see you again, never!" and that's been all. I tried to gave her a letter through her friend but she rejected it and broke it.

I don't know. I feel like I really lost my mind. How am I supposed to feel like this? It's passed two f****** years! I feel upset cause I felt like if she were stalking me it wouldn't matter if try to do the same, if I grow up such gigantic interest on her. I just couldn't draw the idea of her being younger and not understanding my feelings, and I'm sorry about that, but I can't clearly get how am I supposed to forgot what I feel.

Again, sorry for my English. My native language is the Spanish.
