Aren't there single available guys where you live instead of you trying to go after your married boss with kids?
You come off as a woman that goes after what she wants but setting your eyes on someone who you knows is married and acting on it is morally wrong above anything. So that leads me to ask you where are your morals?
What would've happen if he had said yes? You would've put yourself in a hot mess. I am guess he didn't take you up on your offer but somehow I don't think your able to deal with his turn down.
In the future don't approach married men and your bosses. Both of those things are negatives.
