take yourself off of his roller coaster...and just take anything and everything at face value - no expectations, no assumptions, no analyzing - it will help you protect yourself and your emotions. It's hard to get there - but being detached, even with love, can be so very healthy for you.
Don't try to make sense of why he's driving off like he's mad...maybe he is, maybe he isn't...either way...you still have to be the same person for yourself and your kids...For me it was about discovering a healthy way to focus on myself - without feeling like I was being self-centered.
