Allen's right, Antonia - if we could have all seen the signs ahead of time, we wouldn't be here now.
My WH worked out with OW 3x a week for 9 months before I got a clue. How in the WORLD could I have allowed that, you ask? Well, the last time WH worked out with a woman 3x a week for six months, it was to help her get in shape for her wedding. She looked amazing on her big day.
THAT was my mental picture of WH working out with another woman. How in the world was I supposed to know that THIS time, instead of helping the girl get into a wedding dress, he was trying to help himself into her pants?
Hindsight's ALWAYS crystal clear. You can't beat yourself up about it. You can only learn and try to better next time.
