how difficult it is depends on the couple. maybe his is easier than what he's hearing from others. I feel like my marriage is way easier than other folks.

we communicate......a LOT, in order to mitigate huge blow ups. those still happen at times, but they're short lived. no carry over anger or resentment.

there's on going maintenance that's handled on the daily. all of it is inclusive of the kids, finances, house shit, etc. and if there's an issue, bring'em out, bring'em out. clear the air, makes sure everybody's heard, even if the disagreement is still there. admit what I did/said and vice versa. move on to dinner or whatever activity is coming up next.
