Do guys like it when girls are romantic?

I have always wanted a side view picture of my girlfriend's head with her eyes closed. And then take that picture and put it on a pillow case. That way I can feel like she is there when I go to sleep and she is the first thing I see when I wake up. If you think this is something you may be interested in doing then you have to go to a store that sells fabric that can be printed out on a computer printer and also ironed onto a pillowcase.

Another great idea for a woman of your age (if you want to be the secretive type instead) would be to write this guy a letter in pen and paper. In this letter express yourself deeply as to why you think you like this guy and why you think you would be a great girlfriend to this man. Be VERY forward in your words and then sign it at the bottom with your initials. Put the letter in the envelope and seal it. Put on some lipstick and kiss the outside, preferably in the front. On single kiss says secret admirer without actually writing it out. Find a place where he access to the letter but no one else will, for example his locker. If the guy is smart then he'll find a yearbook and start flipping through it until he finds a name that matches your initials. When he figures out who you are, you'll know it the next time he approaches you.

"putting a little heart in his side mirror with a HI next to it" (it can be cute or freaky depending on the situation)
I don't know what you look like so it is hard to say what his reaction would be. Do you think you have a chance with him? Does he even like you? Does he even know you exist? What is the situation here? Guys are all physical. There is nothing worse than being admired publicly or secretly by some girl I have no interest in. Just to be nice, I would try to tell her that we can be friends. If she still doesn't understand, then I would be bothered.
Give me some more information about your situation with that guy so I will be able to help you out.

In 7th grade I had left a poem I wrote in a guys locker who I had a huge crush on since the 4th grade. Of course I was to chicken to put my initials on it. I may have written my name in invisible ink that can only be seen when you color over it with a highlighter.but not sure if I gave him that one.
Years later I regretted not putting at least my initials on it because I found out in my sophomore year that he had a crush on me too in 7th grade. I was a shy girl.still am. Not as bad though.
At least last time I saw him 3 years ago (age 23) I went straight up and talked to him to see how things were, helped I was no longer "crushing" but I still thought he was still a cutie. And he had a little boy that looked just like him.
God I miss high school crushes! TAKE ME BACK! LOL.
