<human>: Can you provide a brief overview of the text?

This is weird so bare with me:  

I used to talk to a guy "Charles" over 2 years ago. We weren't exclusive but he wanted a relationship, it didn't work out because I was busy with school and life. We never did anything just talked and sent selfies all the time. It wasn't serious. Charles did actively pursue me. 

It stopped when his life got busy and I told him he should talk to other people and gave him relationship advice.  

Anyways... The other day I met a guy at a bar. He looked super familiar but I couldn't place a finger on it. Whatever, started talking to the guy.    

So Charles posted a Facebook status and bingo! The guy in the picture is John. John is Charles' little brother. Fuckkkkk!!! That's where I remember him from. So I load my iPad and yep, the pictures Charles sent me from their vacation have his brother. Wtfffff!!!   

Anyways, my question is should I completely dump John go no contact and never see him again? Or should I ask Charles if it's okay for me to talk to his little brother? Seriously.... I need help. This is weird.
<bot>: Guy I'm talking to is the little brother to a guy I used to talk to. This is weird, should I just not contact him and cut my losses?
