Is it weird that me and my ex are closer now than when we were together?

We talk almost everyday and text each other while at work. I feel a kinship with him that I never felt before. I call him grandpa as a joke while we play a card game on our phones.

We just seem so connected now. I wish it had been that way when were together but maybe this is how it was meant to be.
