I'm gay but mom wants me to marry a girl

Going out of the closet was the best decision I ever did in my life. I'm gay and I'm happy for being one. My friends accepted me already, including my dad, but not mom. Yesterday, she talked about us siblings to find that special person for us. And the last thing she said - she wants me to marry a girl. She opened up the topic of being straight, even created a profile for me in that social dating event to meet women for dates. What should I do now?
