We dated 4 years and I didn't meet his parents?

Cece • ❤️Twins Arriving soon in July. In love with one amazing guy💍😘
Hi guys I've dated the same guy on and off for 5 years and now we're married but prior to that he was always hesitant on me meeting his mother and sister. I would ask him why he never brought it up of me meeting them and he'd say, I will one day. Till this day it bothers me because I believe if I weren't pregnant he would've never let his mother meet his now WIFE.
