Ok, Im going to be honest here. I don't care how much GALing you get. That's not going to stop your husband's power and control issues he has.
For me, and this is my personal confession, that the more I acted as if everything was ok with his mood swings and him treating me badly, the more I was putting myself into denial of how bad things were with him.
How he treated you was disrespectful and very incosiderate.
However in the light of GALing I would suggest you get your own computer and not have ANYONE touch it.
