Search Results: a guy thing movie

Ok so I think I know what I should be doing here but I want some other perspectives. Guy 1 is a guy I work with, guy 2 is his best friend since kindergarten. I live in a small town, otherwise I probably wouldn't have found myself in this situation.

So guy 1, when we 1st started working together, was very flirty and obvious he had an interest in me, even tho he had a girlfriend at the time. Shortly after guy 2 added me on fb, anyways later finding out they are friends. So after awhile with guy 1 I backed off, since he had a girlfriend. I didn't want to get in the middle.

Then one day guy 2 messages me, we talk, he mentions how I work with guy 1. So it's not like he's unaware of that we all know each other. So me and guy 2 talk for a month or so before we finally hang out in person one time, we just watched a movie together nothing else. But we have exchanged nudes and such, ik ik it's dumb.

Well one day guy 1 mentions he's no longer with his girlfriend and next thing I know we're kissing, and months later we've had sex. So basically I'm still talking to this one guy, not like very deep convos or anything, so it's not like this is something that would break his heart. But now he's wanting to hangout again.

Do I tell him what's going on? Or just cut off contact? Or even just hang out anyways, it's my body and who I've been with is not his business? Please help me I'm so all over about this I just need some sound advice. So please explain your reasons. And I'm leaving a lot of info out, only cause I don't feel like writing a book on this haha
