My ex's friend started flirting with me?

The guy who was a fuckboy has a friend who told me about his own friend that he knew about the army and lied to me because he didn't want anything serious with me and he also told me that he gave him my Instagram... that means his friend got my Instagram from the fuckboy ex💀 why though? And why is his friend confessing he likes me? Where's the bro code to not fuck the ex or the girl your friend had? Not to mention he texted me today that i was in his mind while i never told him I like him back?
