I probably shouldn't say this but a lot of times women like are the BEST sex partners. They have no sexual boundaries and if you're not careful, you find yourself P'whipped and can't get out. Sure many here, myself included, met or experienced one or two like this in your mid-twenty to early thirty years. LOL, she's not the kind you take home to family T'giving dinner but can't easily walk away from her either.
There are different levels of crazy. Moreover people's circumstances in life are different. Irvin is an NFL player who has a lot more to lose than a sheetrocker. He should have immediately checked out when the DV accusations started.
Women like her are looking mainly for one thing---leverage. DV was significant leverage for her. They are also really exceptionally good making it difficult for a guy to extract himself from the situation.
I have found that many of them have borderline personality disorder. They have a fear of abandonment. You cannot just date one because they won't let you do that. They try to lock things down by attempting to gain leverage on you. Moreover they tend to not have a moral "bottom" meaning that they do not have any sort of morality barrier which keeps them from giving a really low blow to sustain that leverage. They have no moral compass.
They will do anything they need to do to sustain that leverage. A lot of guys are in prison because of false allegations from women who are like this one seems to be. I have represented many in divorce cases and many in criminal cases.
They are easy to spot. I have told clients if you don't stay away from her the next call I get from you will be "hey come get me out of jail". Invariably it happens and they say "how did you know this was coming".
It pretty predictable. That's the bright spot. When you know what to look for it's easy to see coming. Moreover in a custody battle it is pretty easy for a lawyer to create a stimulus that causes them to "spin out" and show who they really are to the court.
