@karinagomez I can sympithise with how you feel.... quite alot actually.
My father wasn't a womanizer, but he was/is a prick.
I am his only son, and he adopted my half brother because back then single mothers wasn't the done thing.
My half bro was ten years my senior.
When my parents devorved (think I was 7 or 8) my supposed father said he would stay in touch, come and take me out blah blah blah ..... He never did.
I spent year upon year tracking him down, he moved alot due to drinking, and everytime I found him he said (and I quote), "Shaun why don't we do this more often?, We shall have to make more of an effort!"... Like WTF????
Anyway, to my understanding of how you feel, for very different reasons I have learnt that my father was a prick to my mother, as far as I know he remains a prick to whoever he now lie's with... and he will remain a prick until death and into the next life.....
If he hasn't died already, I can't wait till the day I recieve the news that he has.... because in my book that will be cause for one huge party, not to remember him by, but to say good ridance.
My heart goes out to how you feel, and yes
you do have a right to feel the way you do.
