What does my ex mean?

Anonymous
When we spoke recently after over 2 years of no contact (he text me through a number I didn't know as he's changed his SIM), he said it really is nice talking to me and he will always talk to me. Does that mean he will always be there to talk, or he always stay in touch?

He kept calling me by my nickname and said there's lots of memories coming back, and he wants to speak again if I want to.
He's moved away from London to a town almost 2 hours away by train, so I know he doesn't just want to hook up. He cut the people he knows from there out of his life, so he said it's strange talking to me.

He said I was his last girlfriend. When covid happened, he struggled with things and took the chance to start a new life.

Is it possible to just be friends?
