Search Results: girlfriend dates another guy

Met this girl (24) online who moved to my city 2 years ago for work and things moved fast. One 3 hour dinner at a restaurant & I got the impression that she was a complete "goody two shoes." We had so many values in common... so I thought :/
2nd date she invited me over and we slept together, which caught me off guard. She initiated everything, but I went with it b/c it felt special. I didn't finish and she said "I'm sorry I'm not very good at this" which got me thinking she had not been with many people.
2 wks later we were in a relationship & the only thing I knew about her past was her one and only 9 month relationship & some dating that didn't work out. A week later at 11:30pm she gets a missed call & text from a guy saying "Hey, I miss you." She explained it was a guy she dated earlier in the year. No big deal she didn't even reply.

A week ago and a text form her ex for a valid reason created another awkward situation, which led to me asking dangerous questions. How old she was when she lost her virginity & how many guys she had slept with? I didn't think I would get unsavory answers, but I did.

She lost her V at 20/21 (not a big deal), told me I was the 8th guy she had slept with & the last guy was 4/5 months before me. With her only being 24 & a 9 month relationship in there I did the math. From the time she broke up with her ex there was an 18 month period where she slept with 6 guys. Very unsavory info, but it gets worse... 2 of them were one night stands where she invited the guys over to her apmt the very first time, the other 4 she slept with after only 2-4 dates and one turned into a friends with benefits situation for 2 weeks :/

We have already BOTH fallen for each other hard and I'm devastated. She feels AWFUL, said she was lonely & admits the mistakes & how stupid she was. I feel like she was only after sex, had no respect for herself, didn't learn from the mistakes & am having a hard time seeing her as the same person I thought she was.
