Search Results: how to act cool upset

What's up guys and girls, I've got a bit of a dilemma on my hands. This girl I've known for awhile and am best friends with apparently developed feelings for me a few weeks ago and I've been in love with her for quite some time. I guess she started talking to this French kid because "he's cute and French" while she was deciding to act on her feelings for me. Last Tuesay I called her up because I was kind of over the whole middle man talk from other people and I asked if I could come over to talk. She said yes, we didn't talk about it up until that point and when I brought it up she said she didn't know what she wanted and didn't know if she wanted to risk the friendship but told me she had feelings for me. We were sitting in the front seat of my truck and her legs were on mine. I kind of grabbed her shirt and pulled it and then let go. She knew what I was implying, leaned in and we kissed. The night ended and I found out Thursday through the grape vine that she thought about it and decided she didn't want to risk the friendship. I was pretty upset and talked to my family about it and they said I should sit down and write her a letter just to get my feelings out that maybe one day I would give to her. We talked Friday and she told me herself what she was feeling and her decision and I decided to give her the letter but I was by no means expecting anything from it, I wrote it for myself and to let her know how I was feeling. I told 4 people that I wrote her a letter and one of those untrustworthy people told someone else and that person asked the girl about the letter I wrote her. She is mad at me now for reasons I'm unaware of but I'm assuming someone finding out about the letter is one reason. I am kind of in the dark but she said we are still best friends she just needs some time to cool off. My question is should I wait for things to cool off then tell her my real feelings or should I just keep it to myself? I'm going to wait for things to cool off either way.
