It sounds like April is going to bring things to a head with you. You want him to be honest with you, you want to know how best to be honest with your parents. Those really aren't unreasonable things at all. I would be careful not to phrase the thing about your parents and his flat as a threat - it might land that way to someone very scared or fragile - but more as an invitation. 'I'd like to know what your preferences are on how we handle things with my parents. They're going to ask me about your flat. About why I haven't seen it. I've no idea what you tell them.' Something like that?
