Exes - do or don’t!

Hey everyone! I want to know what your thought is on ex partners, particularly this situation.

My ex and I dated for a year - almost 3 years ago. He recently messaged me to catch up and we did. Which turned into more than a catch up 😉😏🤤. During that time he said that he missed me but wasn’t sure what he wanted moving forward, to which I said that was fine cause I was looking for more of a friends with benefits relationship, and see how it goes. Day after I messaged him to check up on how he was feeling and he basically went total ape shit and basically started talking about being together blah blah blah but didn’t want to talk to me or spend any time together - because he was pissed off by my attitude (when I simply asked him when we can hang out again). I’ve decided to not message him, let him cool off then take it from there!

And men think women are complicated.....

Can anyone give me some advice?! What should I do?
