Is it wrong?

Soooooo there’s this guy I used to go out with. We ended in 2014. BUT now there’s his friend who I met last week. If I could have his kids right now I would. He so cute. Now the relationship between them is that they used to play on the same football team. They don’t hang out but they talk here and there. Nevertheless his friend wants to talk to my cute self! Idk if I should entertain. I don’t want to be the girl that’s passed around the team. Any advice?
