she will come definitely...
Attracted to you, or the yellow-green glow of radioactivity.
If they told you that they can't be to happy in their current relationship(s). You might want to be a little more aggressive.
For what it's worth, I wouldn't go near her. If she's hiding it from him and everyone who knows him, that's what she's capable of. BEWARE.
People who call me attractive: taken women, lesbians.
