So I have been talking to this guy for about 2 months and he is still keeping me in the dark about everything I have to dig for so many days to find out one thing what should I do? He always tells me that I can ask anything and that he loves me and has told his mom about me but I don't know I'm still suspicious

I need a little more information:
How old are you?
Have you two ever gone out on a date or do you just talk?

We have been a on a couple of dates I talk to him a lot and see him every other day if not everyday
I'm 18 and he is 21

Communication is a big part of healthy relationships. You should sit down with him and tell him about your concerns. He may not realize that you're unhappy. Also it's better to find out sooner or later whether you can handle him being a private/shady person.
