SOS ☹️

Hey everyone i’m in a bit of a jam rn & could use some words of encouragement& or advice. While in college I started talking to this girl we’ve been talking for 10 months and recently started dating (12/1/2017). I’m 19 going to be 20 next monday and this is the first girl i have ever dated & of course my family isn’t taking it soo well 🙄. She on the other hand has dated girls before me & has been through this spill with her family and it doesn’t bother her but its killing me not having my families support. I really love her & she makes me extremely happy but i just don’t know what to do. i don’t know if i can move on without having my families approval but i feel like they should just be happy because i am happy 🤦🏾‍♀️.. please help
