we would cuddle, kiss, hang out, he would take me to lunch and buy me food, pick me up, give me hugs, open doors for me, tell me I looked cute/pretty, tell me he liked me, etc. then after about 2 months he admitted he had only been using me for sex and that he had feelings for someone else and none for me. he said to get out of his life and blocked me on social media. but just the other day I noticed he unblocked me. what does this all mean? does he have feelings for me or not?
