You do have a choice in what kind of relationship you have with him. You can set boundaries. They can decide they don't want to be married. You have the power to decide what kind of relationship you have going forward.
The nice friendly texts -- tell him to not contact you unless it's something to do with S. But only do it if that's what you really want.
You sound confused still and are still doing lots with the in-laws. That's a backdoor way of staying in H's life.
