You have some critical questions for this guy you’re getting serious with, but you’re uncomfortable asking them.
That’s pretty normal.
Asking some questions too soon might send him running for the hills.
Or at least you’re afraid it will.
You don't want to suddenly lob a bunch of serious stuff at him all at once or at the wrong time.
Some of your questions are awkward or sensitive, and the timing has to be just so if you want him to feel safe answering them.
But good questions for guys are part of getting to know him and determining whether the relationship can continue based on mutual trust and honesty.
