I think in any divorce there is self-image damage....it is like a death that we have to go through the steps of letting something go - we did love it (him or her) and we've lost it - so we must grieve. That means looking at the whole picture -the good and the bad. Blame is often used and we don't see the big picture. It's not a he-said she-said thing - something or someone we loved doesn't love us anymore - or wants something we don't. Moving on is the hardest part because we as women cling to our 'dreams' we had when we got married. If there are children involved - it's even harder to move forward because we still have to have contact with the ex.
If there are other people involved (eg. affair) then we also have to deal with those issues.
For me - my divorce was the best thing for me, and i believe my kids too. I have been divorced since 2001 from their father, and whether we want to see it or not, there are reasons we don't necessarily see at the time for the divorce. Often things happen down the road and we are able to look at the situation and say, that's right - we shouldn't of been together.
I had very low self-esteem and to answer your questions, i believe the reason we have low self-esteem is because as women - we often do EVERYTHING in a marriage (and i'm not saying there are men out there that do everything too) but most of the burden is on the woman, children, work, school etc. I had to go back to school and finish my degree, lose some weight, make new friends (because most of our friends were 'our' friends as a couple), and just generally get out there. Learn about what i wanted.
My kids were slower to accept the divorce and even after all this time, i think secretly they wanted us to get back together - even though they KNOW in their hearts it wouldn't work. To them, that was their safety, no matter how bad it was.
Learning and growing is the best part about divorce. Struggling and accepting your new life is half the battle, dating again is quite another!
