The ex wants to have dinner with me

Last night, the ex wrote me an e-mail. He is now teaching at a college in my city. In other words, he commutes for two hours to get there.

He let me know that he teaches there every Wednesday. He wants to have dinner with me.

I did not have a great experience dining with him over three years ago. He broke up with me and I was clearly upset.

I'm not sure how happy I'd be seeing him. There is nothing enticing about meeting with him.

He said that we "always have a good time" together. Nope, that's not true anymore.

I feel that he's delusional, often referring to the good times, but ignoring how I feel and not addressing it.

I haven't responded. I don't know what to make of his message.
