That sums it up rather well, about a change in environment. I don't dwell on the notion that my marriage had failed. I'm not even sure why such a word is what pressures people to stay in relationships that just aren't working out, no matter how much two people try, or don't try. I say don't try because it takes two individuals to look honestly at one another and agree that the other is hurting and both don't want that for the other, so both agree to try to put away past hurts and pains, address what works and what doesn't work and try to embark on a newer, healthier future.
