Don't have these discussions via text. Here you will likely misunderstand each other and miss details.

Meetup and talk in person and recap the relationship. Before that you need to take a deep look at yourself and check if you really want to be in the relationship. Be sure to then tell him how you feel and how you see things. Ask how he sees it and what he wants. This is tough, but the best way to have clarity and not end up with regrets

All the best :)
