Wife moved out to be with her Tour Guide Lover

[Oxford1]

So here now is the letter that DS21 sent his mother after DD3 when she ran and asked for Collaborative Divorce:

I got your message last night. It started with you saying I'm not
picking up because I don't want to speak with you. That is only
partially true. I didn't pick up because it was VALENTINES day. It was
a day for me and my fiance to celebrate our love not hear about how my
parents destroyed theirs. I also did not hear the phone ring as me and
my fiance were enjoying each-others company without phones. I
understand you wanted to wish me a happy valentines day but you were
very selfish to call during this time. The past few days have been
hard and yesterday was meant to help me forget for a short time and
just be happy with my soul-mate.

Now there is something else I want you to understand. I am not angry
that you and Dad are getting divorced. This is something I thought was
going to happen for a long time even if I hoped it wouldn't. What
makes me furious, what makes me lose respect for the woman who gave
birth to me is all the lies and sneaking around. You lied and cheated
not only on dad but on me and my anxiety ridden brother. Why not
separate before all this? You would have saved so much trouble and
heart break. Worst of all out of all of this you are a hypocrite and
the worst kind! You judged my relationship with my Fiance constantly. You
hated that she wasn't Jewish, you ridiculed the fact she was abused,
and you were disgusted by her past relations. I told you these things
needing approval and guidance hoping you could love her as I do but
no, it was always something, just like everything else in my life,
there was always something wrong. What I find so Hypocritical is that
you judged my relationship and the person I was with so harshly on
your sense of "morals". However while you were judging us you were
sneaking around and lying to me, dad, and my younger brother. This just makes me
sick. How could one judge so harshly on moral ground and while judging
be lying and cheating on those she supposedly loves?? You told me once
that Jewish girls were more faithful than others. You were not only
lying through your teeth but you were being the worst kind of
hypocrite. A judgmental person only spitting out these "moral"
statements because I wasn't with the nice virgin Jewish girl YOU
wanted. You have taught me so much from this whole ordeal. You have
taught me that anyone can say anything to anyone even those they love
just so they can get what they want.

I know about the things dad has done but you weren't perfect either. I
know about the fights, about the abuse he may have cause in the past
but there is one thing I have learned. As a person who is dedicated to
another you have to let the past go ESPECIALLY if that person feels
bad enough to want to seek out help to make the relationship work. You
didn't even seek help you lied, manipulated, and tore our family
apart. My father has many flaws, hell I know I have inherited a lot of
them, but he is a good man and a great father. He acts rash in times
of stress and suspicion but haven't you given him every right to do
so? How can someone trust another who lies constantly. My father has
raised me to be a good caring young man, and I would say you had a
good part in that, but honestly with everything that's gone on as of
late, with all of the lies, I question everything you ever taught me.
I don't know whether to take it with a grain of salt or just delete it
from my brain forever. I don't want to see you at my graduation. My
graduation will be a happy time it will be where me and Sonya really
start to have a life and honestly I don't want someone in it who can
lie to their family constantly with no remorse. I hope you have a
happy life with your new family.
