BTM. If you love her that much and she really truely is happy without you. Let her go find this out.
As for the xmas party. Why not just skip it this year. Unless you need it due to sales stuff.
I think the space apart will do both of you a world of good. Your both hurting. First 2 weeks are going to be bad. But after that it gets better and better.
Who knows you may actually begin to heal and truely GAL and improve yourself. Allow your wife the chance to do this as well. Loving detach and be positive about yourself and your life.
