Your anger is totally understandable, and righteous. I can't even imagine how frustrating this sitch is w/children. Not much I can say regarding H's lack of consideration. If I had any insight ...
As for the comp, don't beat yourself up. If you can password it, do so. That's what I did when I realized my H was poking around on it.
Chin up, you are doing well.
