No, you're not his anything. You don't belong to him. You're divorced.
You are your own person. You are an individual with choices to make.
He's playing house with you because it was fun.
He's not looking for someone or something better. Frankly, if he's looking for anyone else, it's someone worse, someone to match his level of immature and selfish.
Stop putting yourself down like that.
It's his loss if he doesn't want to do the work to make a good R with you.
