<human>: I'm 18,she's 17.

We have been good friends for nearly a year. I started realizing I had feelings for her in the last two months.

To clarify, she told me this about two weeks ago and I told her I felt the same way. Great,right? No. She started acting really strange and distant for a few days afterwards. Eventually things started going back to normal, but I still didn't ask her out because I was unsure if i wanted to potentially lose our friendship if things went sour.

Sometimes I see her as just a friend and I think it would feel weird to hold her hand or anything like that. I'm also getting a weird vibe from her but that could be me just imagining things..

This is where I get my doubts about her still having feelings for me. It might sound a tad childish but here goes. She sent me a screenshot of another guy "poking her" on Facebook. She claims it to have been an accident, but I doubt it. It's also a guy I'm sure she has interest in. The next thing are three tweets from her..The first being "not sure how to tell you this.." then "things have changed a lot since Saturday at lunch" (I was the one with her on Saturday for lunch) and finally just "sorry..". Now what the heck does that mean?

I'm tempted to tell her I don't have feelings for her and that I see her only as a friend. Even though I know if she started dating another guy it would hurt. If I were to do this would it be better to tell her in person or just message her it?

Can you condense the text into three sentences or less?
