It's tough. I miss my kids, too. I feel your pain, bro.
I don't miss my ex-wife. ;-)
I lost my job just after I moved into a new apartment (ex lives in our old house).
Things got better. Sometimes in the 11th hour.
I have a great new job, nice apartment and great friends. I'm increasingly seeing my kids more and more. It's more that as I started to level out and get my game back, my children gravitated back to me.
You don't "get happy" right away. Healing takes time. But there are good things in life to be enjoyed. It takes time to settle in your own skin. Divorce is really hard on men.
I overwork. I watch too much Netflix. I've become fat and jolly post divorce. So what? It seems my PMA and "game" seems to attract really amazing women into my life. I've dated a little, though not ready for anything serious now.
Statistically, you have a better chance of getting married in a town full of married people than in a town with lots of singles. Funny ain't it. ;-)
Dude - from the sound of your posts, maybe you shouldn't be dating now anyway. Take some time.
My friend tried to set me up with a Filipina half my age in a long distance courtship. She was lovely, but, honestly I don't think if I were pretty young thing like her I'd want to marry a middle-ages divorcee like me. Didn't appeal to me at all. ;-) IF you marry one, remember, she's gonna want to have children.
