How the partner that leaves just often leaves without a backwards glance assuming that the partner that stays will pick up the pieces and be the responsible one? I mean, what if the partner left behind just thought, "oh bugger this, I'm off too". Then where would the poor children be?
It's just the irresponsibility of it and the assumption that someone else will do it. To be honest, this even applies to men/women who pay maintenance because in my opinion they have the easy job. They just pay the money and don't have to deal with the day to day slog.
In many cases, mine included, there isn't even any maintenance to be had. I am just expected to support our child single handedly. My ex-husband however, now plays daddy to 3 kids who are not his own (he also has another bio daughter who he has left in similar circumstances to us).
Anyway, RANT OVER
If anyone else fancies a rant then feel free!!
