Mothers leaving their children-Am I wrong for judging?

While still making fun filled wedding plans and making sure that his and my child are a part of this festive and wonderful day, it astonishes me listening to a story being told about a woman. She was someone that is; I continue to listen, very selfish and as I became very curious not that brilliant in what she may call her career. How can a mother, mom, mommy find it in her heart to leave a child let alone children to make her own happiness; and really is she that happy? I can see now she was simply a void that didn’t have much meaning and I can see why. To me for most women, it's the one bond they'd never break.
"People say you have a responsibility to your children. Well, you’ve got a responsibility to yourself, if you choose to want to better your life, career, hobbies or whatever you make it out to be, there are still responsibilities in life and that is including your children having them close, letting them know you love and are there for them whenever they call. Getting on a plane once in a great while making that initial visit and heading back where ever you came from must not be a very good feeling and maybe some of us don’t have a choice, but when you do shouldn’t children come first? Maybe I was brought up feeling that I did come first in my mom’s eyes that she did make many sacrifices in her own life for me and my siblings, it hurts of course because she did make so many sacrifices but it made me a better person not only to myself but to my daughter. It really got me to thinking; after all, if it was a man meeting up with his children, I would think: 'That’s really lovely.' In truth, we don‘t view mothers in the same way.
"There are also women who don’t take naturally to motherhood. In the past, they would have stuck to it because the alternatives were few or zero. Now these mothers feel they do have a choice, and perhaps they feel society won’t judge them as harshly as it would have done years ago."
"In general it is always best for a child to remain in constant and loving contact with a mother, but circumstances vary, and perhaps society nowadays does not judge as harshly as it would have done in previous generations." I am no one to judge, but I do question mothers who make selfish choices to live a life that’s really just a fantasy, to choose a man or job over children, well that’s where I do judge.
