Holy cow...

Omigod, I just read all of the responses and your responses to the responses. 

She is a trophy and that's the bottom line.  What do you honestly know about her dealings in Family Court other than what she's told you?  Have you seen Court Orders and evidence to back up her claims about a deadbeat father? 

It would be a very, very smart and wise move if you chose to step back, leave the superficial to the superficial, and begin seeing yourself down the road with this gal after 5 years.  TOO many people put up with behaviors just so they can carry an "attractive" man or woman on their arm, and they end up paying dearly for it, in the end. 

Oy-vey.  Again, best wishes to you.
