I don't mean to be negative, but TBH, from your post, I don'e see anything from her that isn't just cousins? Ok, so maybe the massage request was a bit much... but she is young. If I were you I'd try to stop focussing on it while you're still so young and move on. I've spent 35 years in love with my cousin - I had a lot more to go on in the beginning, but Im still waiting and it's been extremely painful. My advice would be, if you can, move on. Sorry x
My first cousin crush was when I was fifteen. Thirty five years later I am still so in love with him. We've never managed to publicly commit, but we are closer now than we've ever been. I won't give up hope that we can eventually overcome his fear of the family response.
