<human>: I don't know if this is the right subreddit for this, but if it isn't, please could someone recommend a better one for me to ask advice in? 

I am 18/m and around spring of this year, I'm not too sure when exactly, I went on a date with this girl who was previously just a friend. We later later decided it would be better to just stay friends, though I could sort of see that she still liked me in that way. I felt bad about this, but none the less I didn't feel the same way, so I just tried to be a good friend to her and put it behind us. Over the next few months it seemed pretty normal, much like how it was before we went on a date. Though occasionally, especially when drunk she would be very intimate but I would just ignore it because I assumed she just felt especially emotional when she was drunk. 

Then jump to a week ago, we were at a small party together and she  overheard me talking to a friend about a date I went on, at which point she stormed out the room. Later she asked if we could go on a walk together, so we did and mid conversation she stopped and said she is in love with me. 

I didn't know how to react so I said we'd talk about it another time, we hugged and then went back and pretended it didn't happen. I would assume she said it because she was drunk, but the next day we talked about it on the phone and she said she has been in love with me for a long time now. 

I'm not really sure what to do about this situation, I don't feel the same way and it sort of scared me a bit. I know we are only 18 and we're at an emotional age etc. But she seems very sincere about this.

Could you distill the essence of the text into 1-3 sentences?
<bot>: A girl I went on a date with once a few months ago recently told me she is in love with me, I don't feel the same but I don't know what to do about it.
