Mom and Dad divorced... they dated other people, and now Mom is remarried to a guy who is my Step Dad... My brother and I handled it rather well... It made sense... Mom and Dad didn't love each other anymore, didn't love my brother and me any less, and they both deserved to be happy - without neglecting my brother and me. I think I was able to handle that pretty well...
So if I can handle this, then why would a parent try to fool their children or worse, give them false hope that Mom and Dad are going to get back together? Kids are smart and a lot tougher than you think... they can find happiness even if their parents are divorced...
So why is this guy back with his ex, seriously?
"The weakest soul, knowing its own weakness, and believing this truth that strength can only be developed by effort and practice, will, thus believing, at once begin to exert itself, and, adding effort to effort, patience to patience, and strength to strength, will never cease to develop, and will at last grow divinely strong."
