As a wife, I have always said to OWs: you and I (the two idiot women) are sides of the same coin.
The horrible thing R&B, is that they tell us who they are and we don't believe them.
When my H was dick deep in OW he treated me like absolute sh*. Did I believe him? Or did I say to myself (with his help) 'he is depressed and confused, I need to understand him better'. Why wasn't I asking myself, 'what am I doing, hanging around with this person who isn't treating me nicely and who isn't my friend?'
We lie to ourselves, overlook stuff in order to invest in a situation and control it.
You did the same. He was telling you he was a cheat and a liar and was ultimately only thinking of himself by using other people, and you chose to believe it was soulmate love. (Hey, so did I when I first met Mr Sparkle, the only difference? We were both single).
There is no difference between us in terms of self-respect and living our lives authentically.
And our heartbreak is our lesson. Wise up, and get a proper life. Dont' fall for not nice men (who probably fear and dislike women anyway, certainly they have to in order to treat us like this).
