It happend few years ago. Me (22 m back then) broke up with only girl i ever cared, that is until i met this other girl recently.

My good friend set me up with her friend (23 f) for a rebound. Couple contacts, nights out, we end up at after party and get interrupted couple times, so sex doesn't happen. Also we were drunk. I thought that's it. Few days later she invited me to her home. We started having sex, and then i broke and started crying when i remembered my ex that ment world to me. She started hugging me and was my crying shoulder for two hours straight. Later she started crying about her issues and problems. So we ended up leaving often and go and cry somewhere together. People thought we were fucking any chance we got. Some guys were outright jelaous at me because they thought we were friends with benefits.
