Is loving someone is Mistake?

I am dating a girl for 3 years, we both want to get married , her family is not financially strong as mine , my family wants a good family from a good background

My family has seen a girl for me
She is from very good background
She have educated family
Financially good
And can do a very good function of marriage

And

Family of a girl i loved
Average background
Not so much educated, only new generations is getting education
Financially not good
Can't do a good marriage functions
But , only thing is i LOVE that girl truly
And for that
I don't care what she have or not
I believe in making our own empire together
