I (26M) have been dating my girlfriend (26F) for 5 years, and was planning to propose to her next month.

Last night, my girlfriend and I were having a date night and we were talking about our first dates, and reminiscing how we met. We were cracking jokes, and it was a fun atmosphere. My girlfriend admitted that when we were in the talking phase, she was also in a talking phase with 3 other guys, and that I was not her first choice physically, and that there was this other guy who was very attractive, but he had the emotional density of a black hole. 

She was laughing about it, but I did not feel too great about what she said. In fact, I felt awful. Why would she even say that to me? My girlfriend sensed the shift in my reaction, and she apologized. I made an excuse and told her I was tired and was going to sleep.

This morning the whole atmosphere was sort of awkward. I was upfront with her this morning, and told her what she said last night hurt me, and that I needed some space from her and to rethink this relationship. She even cried, which for me was a bit dramatic considering she was the one who hurt me last night.

Can this relationship even be fixed? She has pretty much made me feel worthless after what she said last night. I'm really glad I haven’t proposed to her yet, and am going to hold off on the proposal for now.
