What would you say if one of your friends said to you 'you can go out with my ex' or if any did happen with you, I understand?

It's not a good idea. At one point or another old feelings will stir within them and they will get jealous. Jealousy can make ppl become very spiteful.

I'm doing a relationship Q&A for my next Swear Down TV vid, so if you want my awesome advice ask away....
