We value the same things, he makes me incredibly happy, and i love him.It's not at all that i fell in love with the wrong person, because i don't feel he is the wrong person at all, our only "problem" if any in our relationship is the age gap. As a dad, seeing that my daughter brings home a 40 (almost) year old guy... How important is the statement "age is just a number" to you?They may not like it, but they are more concerned for their baby - you.
His parents know about us and they like me, but i know it will be a big issue with my parents. Because you are going to have to solidify your belief in that statement to sell it to your parents.
If you believe in your relationship, you believe that you are making the right choice and doing the right thing for yourself, then approaching your parents will tough, but manageable.
