Guys, What does it mean when a guy says, “ it’s not a good idea to talk in this moment in time”?

He has told me he loves me in the past and that he wanted to be in a relationship with me but that he still had feelings for his ex. But he moved to a different state for work so it’s not like it would work out. We used to meet up sometimes and we would talk a lot on the phone.

I am actually friends with his ex on social media because we all met at a workshop. So I know her.
