I know this must be so draining for you. I hear so much of what I experienced in your words -- and the same time I recognize in your H the seething anger and frustration he too is going through.
You all have suffered so much stress. We can see it is taking its toll on each of you. You, Irish, have tons of patience, but even that can be depleted by these daily demands. And then when the two of you come together the friction makes it even worse.
I hear your pain, dear friend, in your words to us. It's understandable. I wish I had words of wisdom for you. Words to help you through this painful time. Does one decide to separate or to muscle through to better times? What to do?
I do know that your H needs to get his head on straight. I've been saying that all along. I recognize myself (hopefully my old self, of the past) in his angry-at-the-world abrasiveness. I know that was the sin I made against my own M. I let my aggravations build up to the point that I would become bitter and take my angry silence out on my W. I carry that guilt. Your H sounds like he needs to talk to someone about depression and about anger management -- there is definitely something going on inside him that must be addressed, sooner or later.
I wish there was some resource near to you that could help each of you through this. Didi has asked about church-related services, is that an avenue either of you can look into?
