I’m a guy and my best friend is a lesbian girl. We’ve been best friends since we were 7 years old (we’re now both 31) and honestly she means everything to me, other friends come and go and we’ve both had girlfriends but she’s always been there for me and I’ll always be there for her. There’s a girl we’ve known for a while who my best friend has a massive crush on but I’m pretty sure this girl likes me, I’ve been getting strong signals from her. How can I let this girl down gently without hurting her feelings and try to help my best friend have a chance with her? because I would never let someone come between us.
