Me and my sisters best friend have been talking for a while, she is a lesbian as well as i am. I really like her. She has invited me to parties, concerts and hockey games to go to together. My sister doesn't want us to hangout because that would be 'awkward'. But her friend keeps inviting me and i don't want to be rude!
What should i do?
Go against my sister?
Or blow a chance at a relationship?
