Children is what really breaks us brother. Children are not replaceable like a woman (or a man)..., and they are the innocent party when mum and dad choose to go their own separate ways. We can talk for (not hours you and I), but weeks on end re this deep subject. I've been divorced, and my parents got divorced when I was only 5 years young. Do you have children Darkoz, and if so, do you see them?
Darkoz, based on the few words you've just written, I can say that perhaps the first action you need to take would be to start compartmentalising, or else the load would only feel greater as the days tick by.
