Sandersa - we have both learned that life can be very hard - you have to learn perseverence - learn to cope with hard times. Try not to show your emotions in front of your kids - they are not old enough to understand.
I turned to books on spirituality, bible, great father books, etc. They gave me hope and some strength do deal with a situation you cannot control.
How can someone leave when they have kids ? What is the world coming to ? No sense of committment today !!!
Unfortunately, you cannot control the actions, behaviors, and emotions of your Ex. Don't try to - that will just push him away... The only thing you can try to do is "being" the person he fell in love with. Society has it wrong... It's not about "finding the right person" but about "being the right person" for someone else and for yourself (from a Josh McDonall book) So stop trying to convince him to come back, Instead "Be the right person" toward him so he will want to come back. I need to learn how to do that myself - "be the right person" for my wife to want me back.
