Raffy 💋
Okay basically I had this crush on this girl for ages now but I never knew she was a lesbian. Anyways I started dating her cousin a few weeks ago but I'm not into him and he told me today that is she is a lesbian an had a crush on me. I still have a crush on her what do I do. He proper likes me but I like her and I think she still has a crush on me?? Help? I never even knew I was into girls 😕😕
