"I think we should talk" HELP!

He wants to meet up and speak to me. After 3 months, the guy I was dating, wants to see me. In the beginning I sent some pretty harsh texts and voicemails and pushed him away a lot. But he also left me in a very dark place when I needed him the most so I feel validated. Part of me wants to say screw you and stay home and chat with tinder dudes, and the other half wants to go.. As a form of closure. The thing is, I'm afraid this will reverse all the progress I've made getting over him for the past months.. I just don't know what to do. Does anyone have any suggestions?
