The (26F) ex (29M) demands that we be honest regarding loving and missing one another, and expressing it, despite us being broken up. How can i stop this from happening?

A bit of background details. My ex and I had been together for two years. He had a child from a previous connection, a child who acted bratty, disrespectful and assumed everybody was there to serve your pet. This is more than half of the cause we split. When my ex and I split, he moved out with his child and I stayed at our rental until the lease ended. We stayed in contact psychologically and physically, which I right now realise was a bad idea. To the hard part – I have now moved away from our rental and are trying to settle at my new place. My ex insists that we stay in contact; which I don’t mind; however is very pushy about us “being honest about our feelings”. He insists that we inform each other that we love each other because that’s how we really feel; regardless of me telling your pet countless times I’m uncomfortable talking about it. I don’t wish to hurt him even more, yet I don’t know how to end this example so I can move on.

TDLR; ex partner and I nevertheless love each other but There are no interest in being with him. He won’t end pushing for me to “be honest” about my feelings plus continues to text me informing me he loves plus misses me, and demands I do the same even though it can make me uncomfortable. I want to move on.
