Really disappointed in Davina. I felt sorry for her in the beginning - no family visited, which means she grew up starving for any kind of affection, and is now doomed to a life of needing too much affection from the men in her relationships. That's probably something she'll never entirely get over.
But she's not really taking enough action to toughen up. She is physically beautiful and financially successful, and this gives her an emotional crutch - she can rely on these things to give her a desperately-needed sense of self worth. But it's obvious that she's a house of cards waiting to come crashing down.
Unfortunately, her new husband is in a similar situation, but instead of blaming the world for all his ever-present issues, he shoulders it all onto himself. Dude needs to get some self-esteem, and NOW. And once he gets it, he'll realize what a disaster this marriage with Davina is and run for the hills.
