Caught his lying a**

My bf is cheating and Ik he is, even tho he is always like “oooh loyalty is the biggest most important thing to me” well then why do u text all these girls at weird hours and why does ur social media say you’re single? Hmmmm. And Ik he’s cheating but I have no way of proving it, so a friend of mine (who he doesn’t know) added him on social media and is trying to get him to flirt with her so I can have some cold hard facts. He’s admitted to me that he’s cheated on his exes on multiple occasions, and he acts shady as f*ck like 99% of the time. I even caught him before texting another girl calling her beautiful and stuff, and he came up with some crap story. Oh that was my buddy he had my phone, huh yeah whatever, last time I checked my ID says I’m 24, and I was not born yesterday. So, WhT do y’all think about it.
