<human>: My girlfriend and I just got back together after taking some time off and seeing new people. After about 2 months of this, she wanted me back and I accepted her. However, she wants to keep in contact and be friends with her fling on social media.

I never wanted to take time apart but it had to be done (i wont get into detail). But I cant have her talk to some guy which she had sex with. It just hurts me every time I see the guys name pop-up. What should I do? Should I tell her to block him on everything if she wants to be with me?

Can you give me a shortened version of the text?
<bot>: Girlfriend wants to continue to be friends with fling, but she says they barely even talk. What should I make her do? Have her choose?
