'My dearest daughters, today I say goodbye'

Story here. Excerpt:

'A father who is giving up after a four-year fight to see his daughters has written the two girls an emotional goodbye email, prompting fathers facing similar situations to say: "Remember, brother, you are not alone."

The email has been distributed as far as the US, Canada and Saudi Arabia.
...
"My dearest daughters, today I say goodbye to you, as I no longer have the strength to continue the four-year battle with your mother. I am mentally, physically and financially drained. Please always know that I love you, and that this is no decision on my part," the email reads.

The father said his ex-wife had prejudiced his daughters against him, resulting in "hate faxes" in which the girls said they didn't want to see him. "I do not know you, I do not go to strangers," the eight-year-old wrote.'
