Hi Spyder,
I was in the same situation as you two years ago and
made a number of critical mistakes in trying to achieve a shared parenting
arrangement, which to me (and my son) was the desired outcome. Sadly, the
court and social work systems are set up to prevent what many other
civilised countries view as the best outcome
for children. In the
end, my son and I got 30% of his time, but not before "the forces of hell"
were unleashed against me by my ex-wife (the system also encourages
otherwise sensible mothers to play dirty - be warned!).
Anyway,
the important thing I wanted to say was that there is a long established
and non-militant charity: Families need Fathers, who have campaigned for
shared parenting for nearly 30 years and offer huge amounts of wisdom and
guidance to committed parents like us. I would suggest you have a look at
their website - or give one of their advisors a call, and prepare your case
carefully, before taking any further steps.
For example, citing
her two affairs (my wife had one too) will work against you rather than for
you. It's not about her behaviour, or who is the better parent, it's
simply about what is best for the children.
Good Luck!
BB
