Well you know, people get back together after break ups/divorces all the time.
Like Cyn said, it is forgiveness on both ends is absolutely vital.
So is honesty. Why would we need to smack you to be honest with her? Maybe I'll just smack you anyway.
Don't fear the pain, it can teach amazing lessons, *If You Pay Attention!*
Seems like you didn't really make a break from her though. I'm not doggin' you there, it must be an incredibly difficult thing to do, cut someone out of your life who's been such a huge part for so long.
And just a note, if your standards are so incredible, maybe you should think about applying them to yourself.
