Should I still follow through with my plans?

So here is the situation. There is this girl I like who was in one of my classes. I’ve known her since last year and I say we’ve become decent school friends. We never talked outside of school. We would sit next to each other in class and talk frequently. I quickly noticed I’ve developed feelings for her. I’ve tried to tell her I liked her more than a friend but I would always get discouraged. One of the reasons is that she has a really close friend who’s is not too fond of me. In fact the girl I like’s friend is friends with one of my close friends and he has even told me she says she doesn’t like my personality.

It’s worth it to mention that all three of them know last year I had a crush on this other girl. To keep it short they gave me their advice but she didn’t like me. The whole time they gave me advice I wouldn’t really act like myself and acted foolish and wishy washy and all around immature about it. I couldn’t even talk to this girl I liked, I didn’t really get to her, her interests, and couldn’t tell her I liked her. I tried not to let it dawn on me and got over it. Even though it was a pretty lousy situation I feel a lot of good came from it. Looking back I realize that we have too different of personalities that we wouldn’t be a great match any. I feel I’ve matured since this situation and I’ve learned a thing or too and feel a bit more confident in myself. Not too much. With this girl I like right now I got to actually know her. I made an effort to talk to her as often as possible, got to know her interests, some of her dislikes, got to know her sense of humor(I’ve made her laugh a few times), and she’s even told me basic things about her personal life. I really enjoy talking with her, we find common ground on a lot of things and have similar opinions. When I talk to her, even on topics we haven’t discussed, I feel like we would have the same thoughts and ideas about them and that we like a lot of same things we haven’t discussed.

Back to the present, I got a message from my friend who got a message from the girl I like’s friend that said the girl I like has noticed I’ve been acting a little different lately and that she doesn’t like me that way. She said she didn’t know
what to say so he asked my friend if he could talk about it with me. I felt pretty bad about the news but didn’t discuss it with him much further. In fact the next day she didn’t bring it up and we continued as if nothing happened. My friend also told me the girl I like’s friend says she hates me for trying to date her best friend.I know she’s made her opinion clear and I don’t know what it is that she doesn’t like me but I wanted to her I can still try. I still have this feeling that I should still tell her how I really feel about her and ask her upfront. And she still says no I know it’s time to call it quits.

So I had the idea to write her a letter. A basic one since I know she likes reading and language arts(so do I) so I thought it was a good idea. I basically said I like her more as a friend and that I would like to talk with her more often and spend some time together and if she doesn’t feel the same way I hope we can still be friends. I also drew her some pictures since she’s into drawing and art(as am I). I put everything in an envelope and was planning to give it to her on the last day of classes. But we had such a good conversation that I didn’t want to ruin our friendship. It just so happens that we both signed up for a short summer class and I was going to give it to her then. But again I had this feeling and I thought about the whole situation and whether or not I should go through with it.

I still have a chance to give it to her when classes start again after summer break. But I don’t know if it’s the right move. I don’t want things to be weird between us but I have to get this off my chest. I put a lot of effort into the letter to make sure she knows I care for her and that even if she says no I still have the guts to tell her how I feel.

So what should I do?
