Yeah, I suck at time management, too. After all--here I am on the internet instead of doing MY work.
But I can still tell the difference between my poor time management skills where, despite them, I am on the go 14 hours a day, at least TRYING to get it all done, and my XH who sat in front of the TV for 5 hours a day while I was doing dishes, dinner, cleaning, fixing, kids' homework, etc.
That your time management skills are not the best doesn't change the fact that a marriage should be a partnership, not one parent routinely playing single parent while the other skites around Europe footloose and fancy free.
Regardless...good luck with the path you're choosing.
