Sorry, Anita, I still disagree.
When Dh and his ex first split, he was paying in excess of 80% (YES 80%) of his salary to her to get sorted. Obviously, that has gone down, but he took a MASSIVE step down in terms of lifestyle so that his kids didn't. And, yes, I do believe that, if he hadn't done that, his ex would have done everything in her power to stop him seeing the kids. She's pulled quite a few tricks as it is!!
there is a real difference between one parent trying to discourage / disallow contact and a parent simply walking away.
A parent simply walking away (IMHO - and this IS simply MY opinion) is MUCH worse. Neither is right, but I don't get how any parent can simply walk away from thier child, for no other reason than money or a difficult Ex.
I really don't know how some people can walk away from an innocent child (and I don't mean are forced out - I mean, CHOOSE to walk away) and then honestly look at themselves every morning. I will never get that.
