Huge change in my life coming :(

I went through this same thing January 2013. If you need to talk, pm me. There is life after separation and divorce. The best thing you can do is be a great dad and be on the same page with your wife about your kids.
Oh, and don't blame it all on yourself. It takes two people to make a marriage work and it takes two for it to not work.....you both had a role in the breakup.
