Smile, be positive, be humble, find joy and grace. learn from your past mistakes, pray and ask for strength. Because being a LBS is actually being sick. We become emotionally sick. And there's no medicine out there that can heal it. Only actions, time, and hard work. Only going through the process brings healing.
Onward and Forward. You are doing good, you fell down, now stand back up and dust yourself off.
We are all rooting for you!!!! Go GW Go!
in my opinion, this is not the best advice for you... naturally, you are TOO nice... this is where it gets confusing for you... you need to get beyond the humble, smile, positive... you need to be pi$$ed on the inside and use that to do a 180... i am not saying you need to act angry and mean... but you need to get to that, "i'm not going to take it anymore," place...
she has brought the affair into your home... that is not okay... do whatever you can to not allow this... take away her wifi, her "toys," and don't allow gifts from OM to your kids... and go out there and GAL!!! really GET A LIFE!!! put yourself FIRST!!! you need to do this to get to a healthy place... don't do her any favors... NONE!
oh, and did i say: GET A LIFE????? i cannot stress this enough... when you really do this, it will change you... in a positive way... you will enjoy your time, learn new things, meet new people, and grow... and it will make you more attractive to everybody... most of all, it will get you to a place where you will see you are worth so much more than settling for a mediocre existence...
in the words of John Keating as played by Robin Williams in Dead Poets Society, "carpe diem... seize the day, GW... make your life extraordinary..."
