How can they live with themselves?

Doing in home divorce proceedings right now and it is a living hell. STBXW is high conflict and annoying as all get out. My two kids are caught in the middle of the shit show and sadly they seem to take her side in most things, which I get, because they're home with her all day while I work.

So here's the rub; no sooner than a week after she filed for divorce, she informed me that she would be traveling a few states away to "visit a friend".... I ended up using some of my limited PTO to watch the kids while she was off with her new mister wonderful. She has traveled out of state several more times since divorce proceedings have begun. She is planning another trip in August. Her new guy is 11 years younger than her, and he apparently knows everything about our situation. I will be using more of my PTO to watch thee kids while she is gone, only this time I'm planning to do some fun stuff with them and make the best of the situation. The kids know what she is doing and seem to be cool with what their mom is doing, like "yeah, mom deserves to be able to see her friend"....

To top this off she is asking for full legal and physical custody, with only supervised visitation for me. But she has no problem leaving the kids in my care for days at a time. Like, please tell me this is wildly inconsistent behavior and will be recognized by a judge if we end up in court.

Anyway, how do they live with themselves? How do women have no problem with taking from any man that they can take from? She will gladly try to weaponize her parent's money and the court system to take as much as she can from me while simultaneously getting into bed with someone new, who she is letting pamper and shower her with gifts and vacations and what not. I'm confounded. Shouldn't this make a normal conscientious person feel bad about themselves?
