So, im in love with the sister of a friend, i met her 4 years ago, never talked to her that much, just saw her now and then, after a while spending some time with her because i started showing up on my friend's house frecuently, i started to like her and catch feelings for her, the summer this year, i went to a little party with my group of friends, and she came too, long story short, we got a bit drunk, and we went to bed together, we didnt have sex, we just cuddled and kissed a bit, i was happy as fuck, next morning tho, she was as distant as usual, not that i expected anything else tho, untill this day she is the same, i dont know if she regrets it and pretends nothing happened and hopes for me to do the same, or if she actually likes me, i never got the balls to ask her out or talk about the manner with her, with the time i started to loose my hope on her, but recently, my friend told me to go to his house, because his sister wanted to be DM on a dungeons & dragons campaing, and she wanted me to come, sadly i was busy and wasnt able to assist, tho, the fact that she wanted me to come got my hopes up again, am i just being a fool and try to forget her or keep my feelings for her?
(sorry if i mispelled anything, english aint my mother languaje)
