I'm a little bit like you but don't see it the same way.
At the beginning of our relationship, we shared responsabilities but as the years went by, situation change. He got a job away from home and came back on week-ends only so i had to take on a little more. Then, if i wanted to have some quality time with him, i would make sure that everything was taking care of so that he could relax on his days off and we could be together. After many years, EVERYTHING BECAME EXPECTED of me but became to much for me to handle on my own.( 4 kids ) I started complaining to him and instead of stepping to the plate,he left me and became extremely emotionally abusive. Don't get me wrong, i know his triggers.( It's MLC no doubt ) He also had way to much on his plate but kept me in the dark. I got lucky and discovered everything in the first few weeks of his MLC witch helped me understand what was going on. I knew it had nothing to do with us. In my eyes, our little R problems were normal and easely fixable.Nothing worth leaving his family for. Exspecially at the age our kids were at the time.
