This was my exh, he was so full of hate and anger towards me. Sometimes I think it was separate from his addiction and sometimes I think he would cause the anger/fights to justify getting high. We've been divorced for 2 years now and I don't miss him!! We do share 2 young kids who he sees every other weekend and they are starting to say they don't want to see him (well, my older one, who is 9 years old, is saying this). I feel for them, because he really is just miserable.
No one deserves that, please know that.
