Been going out nearly 2 years. Both early 20's in small state. I was away on vacation and I found out through certain snapchat stories that her and this alpha guy in her group of friends were together alone outside a bar wandering around the streets for at least an hour or two. She was adamant nothing happened, going to lengths to prove it like texting the guy when I asked her to. However I heard from another girl who I believe that she had kissed him but he didn't really reciprocate it. Not sure what to do, there's been little things like this all our relationship like flirting with other guys etc but then she treats me like a king when i'm there. Considering just ghosting her or using her for sex only? what do you guys think? Or ghost her after saying something like 'fuck it its over' or inspire hope by saying 'we're not right for eachother right now' and then leave forever? kinda new to all this TRP stuff and if i'm honest i'm not even that hurt by what she did I just feel sort of relieved I won't have to put up with the doubt anymore.
