<human>: Can you provide a brief rundown of the text in within 3 sentences?

So here's a bit of a back story: My friend and his ex have been broken up for almost a year and a half. Since they've broken up she and I have become better friends.

We're both mid twenties but we live in different cities. We've connected very well, so I've thought, on an emotional level. We talk for hours in deep conversation on the phone some nights.  There is a ton of sexual tension, when we hang out. It is to the point where other friends now make comments said tension.

There are a few problems. I'm about a 5 or a 6, where she's easily a 9 or 10. I'd be breaking "bro code" by making a move on her. If I attempt said move, and it isn't reciprocated, our friendship becomes awkward and possibly ends.
<bot>: I think friend's ex is into me, I could just be a "cuddle bitch" and I'd be breaking man law by trying to get with her. What should I do?
