Welcome to Wikivorce, although Im sorry you have a need to be here.
Christmas is a particularly difficult and emotive time time of
year, especially when you are separated from your children. The time you
did have with your children this Christmas Day, while not long enough, was
I hope, memories made to carry you through the next few days until you see
them again.
I can't answer why your x2b decided that you
couldn't come to the house to see your children, only she will be able to
justify her actions.
As for moving away, hold fire with any
evasive action until you can think more clearly, and the dust has settled.
To act in haste now could mean a lot of heartache in the future. Use your
time offshore to think through your options properly, which could include
family
mediation to work towards resolving the issues
around your time with the children.
Life shouldn't be hard or
painful, but sadly, it often is, but the pain will ease with time, hang on
in there.
