Ok what I'd like to say, that for me the first step that helped me really start to make my way out of feeling so horribly crushed was to really accept that his MLC was not my fault.
If you read through all these issues in this thread you will see how their behaviors will start to make you feel like this insanity is all your fault.
If you're a compassionate and empathetic person, like I am, this will hit you even harder, and the ability to not internalize this is pretty impossbile... up until you get a life line such as this thread and this reading material to shed some light on the real truth of what's going on.
My XH's MLC and anyone else's MLC really is all about themselves and serious issues their psyche is trying to process and be dealt with.
The only way I was able to understand that was to READ, READ, READ. This particular thread helped me immensely for my Xh had all but maybe 2 of these issues, and still does.
Im a concrete details kinda person. So for me, reading this and the pieces just clicking together like wildfire helped me to see that this wasn't my fault. This really is what was going on with XH (H at the time).
Through seeing these are issues with him, I was then able to start working on the other BIG thing to bring me one step closer to THRIVING.
