I am about to ask my cousin's crush on a date… 
Should I do this, and if yes, how should I tell my cousin?

My cousin and I are close friends. 
Three years ago my cousin fell in love with his best friend. He was convinced she was the love of his life. He confessed his love to her twice, but both times she rejected him. This was a very painful experience for him.

Around that same time, even though she didn't really know me, my cousin's crush got my phone number through a mutual friend and suddenly called me to meet up. She came to my place and we had a wonderful evening that just didn't seem to end. We talked for hours, and for the first time in years I had butterflies in my stomach. However, I did not make a move since I did not want to "betray" my cousin.

I have not contacted her since, because of the same reason. We bumped into each other a few times (one time was when she visited my cousin, and I think she asked my cousin to invite me), and every time I saw her we clicked. A friend said that it seemed like she liked me as well, but I just can't tell. 

My cousin still has feelings for her. 

The question is: should I make a move, and if yes, how should I tell my cousin?

Pros:
- I really love this girl (and I don't feel often like this)
- She rejected my cousin and nothing happened between them, so I feel I won't break the "bro code" 

Cons: 
- My cousin will probably feel hurt and betrayed

How should I handle this?

Thanks for your advice!
<bot>: My cousin was rejected by his crush. I love this girl too and wonder if I should make a move, and if yes, how to tell my cousin.
