I want to meet my ex for a few drinks
Do you think that this might be a bad idea?
I do not think it is good for my mental health
It is okay to still be friendly with your ex but it is bad to get involved with them. Especially when you know it is bad for your mental health.
That's stupid. I do not have to follow your advice.
You do not have to but I think that it would be helpful. We all know how bad it can be to get involved with your ex.
