I she into me?

So the other day I ran into my best friends ex-girlfriend at a bar...We've always gotten along so we started talking...we ended up having the longest conversation about their relationship and how the hurt one another...apparently she needed to vent; She let me know how much she misses him, and that she really wanted to get over him. We were having a good time and we were both drunk, she started dancing with me and whispered in my ear that maybe she should get with me...she said: "Maybe I should try and be with you, you would definitely treat me better than any man...I've always thought about it".

I don't know why...but that really messed up my mind. I never thought about her in that way...until now. She is beautiful and a really nice girl...pretty much everything I've ever wanted, I guess I always knew she was out of reach...she was straight. I'm not sure how i should interpret what she said...was it a joke?, was she being serious?... drunken words are sober thoughts...right?.

Its not like I would be with her, she is my best friends ex...that would go against everything I've ever believed about these kind of situations... I just wouldn't do it, Its not me.
But I still want to know...do you think I am over thinking this?... should I forget about it and let it slip?

Thank you for reading this, and for sharing your thoughts...I really appreciate it.
