I have a friend online who divorced her husband because they just couldn't stand being together anymore. I was shocked when I learned about it since they were all so lovey-dovey before. I guess you just can't really tell, specially when trials/challenges comes along. She was given custody of their child, and her husband also had father's rights when it came to their son's well-being.
I know my friend had a hard time adjusting to her life back then, but she felt that she wasn't happy anymore, and so had to do what was for her the right choice...
Honestly, am not sure if I would have done the same thing. I guess it also depends on one's culture and beliefs. Divorce is unheard of in my family and the couple just weathers everything that comes their way ... together.
Life isn't all a bed of roses. We just do what we feel is right. And as much as possible without hurting others.
All of us. :)
