So boyfriend doesn’t answer your questions and doesn’t comment yet wants to marry you. Do you want a husband like that? That would be a pretty miserable situation. Do you ask him questions but he just sits there? Not responding? What do you do when that happens? Is he online boyfriend, not actual face to face communication? If it’s real life relationship, it’s absolutely insane if he just sits there.not responding.

I don’t know about cutting off but personally I wouldn’t want a boyfriend who doesn’t answer questions. And I’d sure don’t want to marry men like that

You seem to really want to understand why people do what they do. You can’t understand as you aren’t in their head. Just observe their actions. If something is not ok with you, move on
