Hey man, stay strong! Really you have 2 children be strong for them! I'm dealing with being cheated on as well, it's a horrible thing that I never wanted to experience and well it's here gotta deal with it. You can do this! Really! Tell yourself (this is what I do) "YOU ARE A GOOD MAN! YOU DESERVE TO BE HAPPY! YOU DESERVE TO BE LOVED THE RIGHT WAY! BE STRONG! BE HAPPY!" I'm going through the process, it [censored]! But I'm more interested in finding me for my kids!
Man you just gotta find you.. DO FOR YOU! MAKE YOURSELF HAPPY, LOVE YOURSELF! SHE'S THE ONE LOSING OUT!
Take time for you and do for yourself! make yourself happy, enjoy yourself! you're a good man you deserve to be treated as such!

Good luck man stay strong!
