I’ve been seeing a girl for two months now. I really like her and she really likes me too. She’s basically waiting for me to ask her to be my official girlfriend, and I know she’ll say yes.
Yesterday she came over to my house, met my mom, and it went really well. We hung out here at home.
Next week, she wants me to go to her city to meet her parents.
My question is: I ask her to be my girlfriend before going there, or wait until after meeting her parents? Or I ask her parents for permission first?
I want to do things right and make a good impression. Any advice?
