Is my friend's Dad a wuss?

I have made the biggest mistake of my life by deciding to move in with my friend and his family following a divorce that costs me almost everything, financially and otherwise. My friend's Mom and Dad have been at each other's throats for years (I fact I did not know before moving in), and it all recently hit the fan when it was discovered that his Mom has been stealing money (and using it for whatever) and not paying the household bills. When she was confronted, she decide to move out on her own accord. After she left things were very peaceful. However, she returned after only about ten days claiming it is her house and she should not have to leave (mind you, she left on her own). Since her return she has slowly eased back into her routine, and has not addressed any of the bills she failed to pay (which resulted in the utilities being shut off). My friend's Dad had to pay all the bills down, and clean up her mess. She feels that she did nothing wrong, and walks around the house like she is some type of goddess eating and drinking all day long. From my vantage point my friend's Dad is a coward, and needs to step up to the plate and do something about his wife's behavior. I only care, because all of this affects me. I will be moving out soon, so I will no longer have to deal with their crap. Nonetheless, I just want to know if my friend's Dad is a wuss?
