Sorry you're having dreams you don't want to be having, Wing.
I hate it when my sleep is disturbed, too.
Therapy might help you sort through some of the unresolved issues that are keeping him so active in your subconscious.
Are you doing any Al Anon meetings or other support groups too?
I'm sleepless tonight because of my health issues and my obsessive thinking kicked in and has kept me up. Ugh. No fun either.
I don't have answers for how to make those kinds of dreams stop, but I just wanted to write you and say hi and let you know you're not alone. And you definitely can recover. It's a process and we can all do it. I really believe that. <3
