I know MLC (a.k.a. MONSTER LIFE CRAZINESS) is crazy. The only thing for sure with it is the H/W is unpredictable. The only way I have been able to make it this far is I see my H as sick. I cannot leave because of in sickness and health. It is very hard, but try not to blame yourself - you did nothing wrong. Regardless if you had been perfect, or not in your W life - she still would have this MLC - nothing you could have done. I bought into everything was my fault until my H blamed his childhood on me. UMMMMMMMMMMMM not possible I did not meet him until late 20s.
You need to get off their rollercoaster ride and watch from the sidelines (I am still trying to do this.) I am actually finding some things that H does funny. The other day I was talking to a friend and said the only commandment left is murder - so I think I am good, there is nothing else he could do wrong, just repeat other sins. I was wrong! I caught him watching porn. I just bust up with a huge belly laugh for about 15 minutes. He came into my room to check on me. He actually got all monster because I did not get mad that he was watching porn - does that make sense?
My H has gotten so bad with the lies that he is now believing them as reality. He really lies about 90% of the time.
