Just Friends or holding onto hope?

Together 3 years, child together. Recently found out he confides to his ex about our relationship and he messages her saying she’s on his mind. Says she’s just a friend.. . is this the truth or is he holding onto hope for reconnection? She broke up with him. I didn’t even know they spoke, when I found out I said I was uncomfortable with it and he said “idk what to tell you.” I’m not one to be insecure but he never even told me they spoke. I don't know what to think and I’m 9 months post partum.
