Do you think I have any chance at all with this girl?

I ve known her for a long time, there is a big age gap, I am friends with her older brother. I actually got the feeling that she was interested in me awhile back but I am afraid to do anything because it s a delicate situation.

We were both at a gathering and her brother was playing guitar along with another guy who he knew but she didn t. She was sitting and listening. The guy was a bit flirty towards her. I wasn t sure if she was interested in him. She talked to him in a different way than she talks to me, but I don t know if it was interest or politeness to a stranger. She plays guitar. I have zero musical ability. The guy kept pressuring her to play something. I have requested that of her before but I don t pressure her, out of respect.

We were getting ready to leave, she was standing next to the guy, and her brother was on the other side of the guy. She said goodbye to us all. I wouldn t say the guy paid alot of attention but I dunno. She seemed to pay some attention to him. I gestured like a big hug to her and she held up her hand like a high five. I said ok I guess that s what we re doing or something and high fived her. She went off to find the rest of her family.

A few minutes later she was walking back by and she sees me and says "ok [something]" and gives me a hug, but it was kind of awkward.

I don t think she is the type to flirt with someone to make someone else jealous, just putting that out there.
