When is the "right time" ?

Hey Everyone! Buckle in this story is a long one and could really use advice. I dated this guy for 4 years, we broke up in March and haven't spoken since. I reached out to him recently to see if he wanted to "catch up" as friends. I trying the slow (lets see where this goes) approach. He says he wants to catch up but at the "right time" and that he is stressed with work cause he wants to make sure it goes in a good direction. My logic is work is always going to be stressful, and if an opportunity presents itself takes it. Can someone translate to me what exactly does he mean by this? Is he just stalling for more time and is this worth the wait a all or should I just move on?
