Hey I need some advice
So this guy that I used to date like a year ago we are now like best friends but I guess I’m not completely over him I have dated since and am actually happy with someone else right now but the guy I used to date we’ll call Bob asked me if I could talk to this girl for him. Now this girl and I get along but she can cause a lot of drama and is a little bit or a lot of a brat. Now I thought I was over Bob but when he asked me this I just started to get sad and cry, now he did ask me over text so I said sure I’ll help him out. But I dont really know what to do now… can you guys help me?
