Bragmatic, I know exactly what you mean about 'damage'. What an offensive phrase! And yes, what does it mean? How do we quantify it? My dad died when I was very young, my sibling died when I was a teenager. My mum remarried, our step-family wasn't an easy one and there were many emotional things to work through. Do I consider both me and my siblings to be damaged? Bloody hell no! It no doubt changed us, upset us, shaped us, affected us. But the word damage when used in this context of parents not being together somehow implies 'beyond fixing or difficult to get over' and I just don't think this is fair. Families have to endure all kinds of things, not just divorce or separation, and it shapes us, for better for worse, and does affect our resilience. Maybe some couples do throw the towel in too early, who knows, who are we to judge when we haven't walked in their shoes?
However, I think in circumstances such as the original poster has described, it is awful the level of guilt mums are made to feel, the way society threatens us with 'damaged children' if we dare leave unhappy marriages. As many posters have put, by taking their children out of unsuitable environments, they are in fact doing the very opposite of damaging their children and are showing great love, care, foresight and putting their children's welfare at the very top of their list.
I've been following this thread with interest, as am (yet again) working up the courage to ask my husband for a separation. What keeps me hanging in there? The children. Today dad has been wonderful, happy, playful, calm, helped them with their homework etc. In the week, he was name calling, unkind, stressed and miserable. I do know ultimately I will have to make a decision for me but gosh, when I think of the 'damage' I could be doing.....
Hope this makes sense, trying to type with interrupting kids never makes for the most fluent of posts but I felt strongly about this and wanted to chip in!
