Is it wrong to talk to your ex's best friend?

Hello everyone, I was in a relationship for 4 and half years and he confessed that he cheated on me with a much older woman. He used my money to go on holidays with her and when she dumped him he came back and confessed. I had to move on cz it was too hard for me. Its been almost 8 months since our break up. Soon after our break up he started dating an air hostess who is much younger to him. He uploads cheesy pics with her on viber cz that's the only place I haven't blocked him.He keeps liking my pictures uploaded on my sister's facebook. His best friend lives abroad and he calls me at least once a week to check on me. His father is known to my father as well. He is a nice guy but I feel bad about talking to him . I feel like I'm betraying my ex. We are only good friends but I'm also worried that he must be passing my information to my ex. I haven't had any sort of contact with my ex for about 2 months now and he hasn't returned the money he owes me until now. Such a messy situation. Please help me. Thank you!

Hello, You may be right, maybe your Ex's friend is passing information to your ex. But also he may just be seeking your honest friendship, I don't consider this to be a problem unless it bothers your ex because it would destroy their friendship. You need to start thinking that your not betraying your ex, your not in a relationship anymore, which means you can talk and see other people like he does. It does seems like your ex is trying to get your attention but you always have to remember what he did and that he is with another girl. I hope I helped, Good luck!

Your ex is not your problem. Don't feel bad and do what you want to do.
