I'm married to an amazing woman but I'm not happy
Why are you unhappy with your wife?
Because my parents didn't meet her family
As long as you love your wife, you should be happy with her even if your families haven't met.  There is always time for them to meet, and even if they don't get along, you and your wife will still love each other.
I feel incomplete without my parents meeting her.
You shouldn't let something as inconsequential as a meeting with parents to affect your marriage. Be happy you found someone who is a perfect match for you.
