Yes. End this wallowing. End this whining. End this constant checking of social media. You're not listening. Social media is your problem here. You, like most others, are addicted to it. Get off, now! If the guy is a legit chad, and you're not, then I hate to break it to you, but you're shit out of luck. She will stick with him and not give you a second glance. This is how it is with younger females. You should let this go. And how old are you by the way??? Early 20's.? At that time of my life, I was at bars, clubs ,beaches etc... looking for one thing and that one thing wasn't a relationship. I think you're so obsessed with this shit, that you're gonna start to stalk and develop a crush on this chad who is banging your ex.
