Welcome,
I have been in your shoes. My situation, however
was with my ex wife. I am gone a lot. I live in a
different state than my ex. For the first couple months
after filing for divorce, I went through much the
same emotions that you are more than likely
experiencing right now. So is she...
I would go to visit my daughter, and my ex would
come on to me... she would say the words I needed
to hear, and one thing would lead to another as you
said. But when it was all said and done, the problems
that caused our divorce were still there.
It took me a while to finally realize that it wasn't
her, and it wasn't me... neither one of us were
in the wrong.. we are just both human. It is very hard
to erase the emotional bonds created by a long term
relationship.
I had to stop putting myself in the situations that
would lead to such activity... it was hard at first.
I still care very much for my exwife... but now it is
more of a sisterly love, and respect since she is the
mother of our child. We still see each other from time to
time... and yes the temptation is still there. But now
I am older, wiser and having realized it for what it was,
I don't fall back in.
Something else that really helped for me, was that I
realized that it was not fair to my daughter for me
and my ex to carry on like that. It was confusing for
her, and slowed the healing process that MUST occur when
a family is divided.
Good luck, I hope this helps.
