It's very possible. It will take time and patience for this to happen. You girls will need to go out, hang out, and share secrets. Only when someone is 100% comfortable with you, are they willing to cross their boundaries. This involves you girls visiting each other's homes, sleeping together (as friends) and almost acting like a couple.

Us guys call it a bromance when we feel like this. A straight friend of mine once kissed me when I least expected it. It made our male bond stronger, and we kissed several times after that. But he is married now to a woman and with kids. I always saw him as a friend, not a boyfriend.

You can do it. I believe in you.
