Girlfriend still talks to summer fling/friend
I need some help figuring out how to handle this/if I should be worried. I started dating this girl the first week of school, and things have been great. We work almost perfectly as a couple, and the last two months have been the best two month of my life that I can remember.
But something has been making me more and more uncomfortable as time goes on. She had a fling over the summer, and she now considers the guy a very good friend. He lives a few states away, but they still text most nights of the week. She says that she sees him as a friend, and that their fling was a friends with benefit arrangement. However she agrees with me that he probably got attached and has feelings still. She told me I shouldn't feel threatened by him, and that he is her only friend that has been respectful of the fact she has a boyfriend.
One thing that bothers me most is some of the texts I saw.
Him: If you didn't have a boyfriend I'd have something else to give you in a bow
her: hahahahaha
On a different date:
Him: (random stuff) ...I'd do you.
Her: You already did haha
Him: Yeah right. JK I enjoyed the sex.
Her: So did I.
Then they went back to normal conversation
My girlfriend is very open and nonchalant about the past in the first place, so it doesn't really surprise me that she would openly talk about that stuff. And it doesn't look like she's flirting back sexually. But it still bothers me a lot. She doesn't know I saw the texts, so I don't want to bring that part up (I feel bad for snooping a little). I'm just really bothered by how often they text.
So what do you guys think I should do?
