If you're still thinking of leaving maybe you're not done. Consider this.
I'm working with a couple right now Kathy who says he cheated and Brian who says she left. Brian insists that before she left he wanted to marry her but now no longer has the feeling. Kathy says she cannot trust him. To say the least they are having trouble getting back together even though a part of them wants to otherwise why would they be talking to me.
The ironic things is when you love someone all things are forgivable. One because if you love someone you want them to be happy even if it's not with you. You realize that all people make mistakes including you and it is not the mistakes you make that end relationships it is how you negotiate after the mistake that decides the outcome.
Brian thinks he can't forgive Kathy because she left. The one question his pain doesn't allow him to ask is why she left. And even though she has explained to him why she left his pain doesn't allow him to hear it. The problem is not that she left people get mad and leave all the time it's the wound it touched in him. If it's hysterical its historical. If it's about your pride it's about your low self esteem. Confident people don't expect perfection they are focused on the solution. They realize that other people have the right to be, feel, think and share their way. Read A Life Of Love.
It's sad to hear people who love each other end relationships over what they believe is unforgivable and what their well meaning single friends agree with them is unforgivable. Nothing is unforgivable to love. The question is what are we going to do now. Our wounds are healed when we walk through them. We forgive people because it heals us and it is to painful to do otherwise. Love makes it safe enough to face your worst fears and recover your innocence.
Bitterness, resentment, and being right doesn't heal you. Happy ever after doesn't heal you it's the hard moments we don't run from that heal us, that give us back ourselves. Wherever there is love I will work like a dog to help people keep it because it's so valuable to them even though they might not believe it right now. If you've ever loved someone there is always a chance. If you want help contact me.
P.S. If you've ever had chemistry with someone there is hope. For difficult situations http://jamesallenhanrahan.com/coaching.html
