I may be run off the board for this but I'm going to say it anyway. There haven't been any consequences at all for your H's behavior. You have never went dark, you have half heartedly GAL. Why would he stop when he knows he can do it and you won't leave? He expects you to get upset, make threats and never follow through with them.

I am not saying file for divorce. I'm saying stop making empty threats and do something about it. Go dark, GAL, let him know what it feels like to lose you.
