I brought a date to a party and this girl who has frustrated me for years was there. She was extremely happy and welcoming of my date, shook her hand, smiled, said "nice to meet you". So this girl doesn't feel anything for me, right? I just want the reassurance so I can rest my conscience at ease.
I didn't do this with the intention of making her jealous, it's just something that came up because I want peace of mind. I actually moved on and started trying to find someone else. I just want to be at peace.
