Appreciate the response. Amount of sex partners can affect the ability to pair bond though, and unfortunately it seems like that is the case with her :(.
But yeah, her having unprotected sex with another guy and not telling me till much later, definitely hurt. Definitely questioned things, but again it's so hard to be logical when you genuinely like someone.

Those messages were very cold.... I was in training when the whole Russia/Ukraine thing kicked off and I have relatives on both sides. I was pretty sleep deprived and stressed during most of the training and it showed when I came back.
6 guys thing, it's that they were all one night stands over a short period of time and it hurt when I found out.
But the fact that she almost had a kid (unintentionally) with a guy during our break hurt the most.
Thanks for putting a logical spin on this. It helps.

You are not wrong. I have a hard time being logical and pragmatic when it comes to relationships.
