I showed my friend my ex's Facebook pictures one night when we discussed women, and he seemed very interested. I didn't think much of it, she's an attractive woman and we are still really close.
Later he set me up for a date with this lady, but nothing really ended up happening, now he wants to get with my ex. He doesn't do relationships, just flings and hookups.
He's saying I should do him the favor cause he did it for me and would do it again.
Should I even approach my ex about this? Should I try to help him?
