Poor fucking guy

Girlfriend and I have been together for a year now. We aren’t living together but have made plans to move in after our leases expire.

Her friend Alyssa was over at my apartment with her boyfriend and some other people. I was talking to Alyssa one on one and my girlfriend was in ear shot of us.

We were talking about some topic and it came to Europe and she told me that they slept with a bunch of super hot guys. It seemed that everyone tuned in then. I laughed it off and didn’t make it into a big deal.

We talked later and I asked her about what happened when she went to Europe. She had previously told me that she only been with three guys.

Long story short she and her friend when they went to Europe would sleep with a hot local guy every city.

It changed a lot of things about my perception of my girlfriend. She really tried to push this image on how she isn’t like other girls that sleep around. When we saw each other she didn’t even want to sleep with me for three months until we were official. And now hearing how she slept with guys hours after meeting them bugs the hell out of me.

Also before I felt that we were on equal footing dating experience wise. Now I’m realizing she has a ton more than I do and it makes me feel uneasy. That too and just the types of guys she went for.

Also it tells me there is a lot she is likely lying about too, if she lied about this. I don’t think Europe is the first place she slept around. I didn’t tell her this but it’s on my mind.

I don’t know it feels like for me, that she was someone that had her fun and now doesn’t want to do much now that she is in a relationship. I before just thought she was a reserved person but now it’s more like is she just reserved with me?

I am not planning on breaking up, but honestly it is putting a lot of doubts in my head. I am at the very least thinking of holding off on us moving in together. Am I making too much of this?

tl;dr - found out information about my girlfriend now thinking of breaking up
