I'm dating my ex's best friend
Does dating him make you happy?
Yes, I really like dating him.
It's generally not a good idea to date the best friend of your ex because it can be a really messy situation. Dating your ex's friend could cause a rift in their friendship, which could also be bad for your new relationship. I would be careful about continuing to date him.
Nah, I think it's going to be fine.
I really think you should reconsider. Can't you imagine how hurt your best friend must feel?
