Should I stay or should I go?

One morning this week I got a text from a man I used to go out with. I have not seen him for 6 years but every few months we swap drunken texts. I just cannot bring myself to delete his number.

He has invited me to lunch on Sunday and I immediately responded "yes".

To say that this is a wrong thing to do is an understatement-we really cannot/should never be together but I really want to see him.

I am already having 2nd/third/fourth thoughts.

I wonder if I will meet him?????????????????
