She passed by "habit" on the highway a while ago and she's deep into obsession county. But is she in any danger from her Facebook fling? No, probably not.

She's not willing to discuss limiting her time on the computer. She even kicks our kids off the computer so she can go back on, and they barely use it. She simply isn't reasonable anymore. And if I cut off the internet service - which I don't want to do - she'll just see it as another attempt to control her.

I actually had a program on our computer that shut off the internet at midnight. I told her about it ahead of time, and that I thought it was important, if nothing else, that she get a decent night's rest. She was pretty angry, and eventually told me to remove it. And, to avoid a blowup, I did.

The thing is, it's not the use of the computerper sethat's bothers me - it's how she uses it to have an affair.

I've always been able to be fully, unconditionally supportive through her depression and psychosis before. I mean, she did stuff that waswayout there - digging up our dead pet cat from the back garden because she was convinced if she gave it a bath it would come back to life, for instance - but I loved her, and I took care of her.

But this... I can't stomach this. She says her feelings for me just turned off one day, like flipping a switch. And she's always been afraid I'd cheat on her, stemming from a violent, adulterous first marriage, so she was always afraid I'd cheat on her. I never did, but I struggled for years for her to convince her I was trustworthy. And now she's betrayed me.
