Love will come again. Not now and maybe not soon, but eventually when you are ready you will find it. You just need to concentrate on you and your kids for now. They need you most (and they will need you even more in the next year or so... they will need your undivided attention and love). Love yourself.
Girlfriends, even wives, may come and go, but your children will be your kids the rest of your life.
There is no arriving, ever. It is all a continual becoming.
