Don't give up. You've made it this far, keep going. You love her, don't forget that. As for your anniversary, why can't you celebrate the 9+ years you had with her. Take your sons out to dinner. Enjoy the day. Just because she isn't there right now doesn't mean today can't be about remembering the good times you had. Each day is what we make of it. Choose to be positive and happy.
I am a religious man. I am available at all time to talk about it with you. I have been praying for you for a few days now.
