I agree with woe-be-gone.

You are doing a hell of a job keeping things professional, as I imagine dealing with this at work must be difficult. As someone in management, I know how much time is spent with co-workers

As someone who has been through the ringer, I think actions speak louder than words. Keep it clean at work, and try to talk to someone who is empathetic. DO you have an EAP?
Employee Assistance Program?

I'm about to use mine!
