I have a friend in a similar situation, his mother turned him against his Dad.
He got married, then chucked out, having nowhere else to go, he just turned up at his Dads, was invited in and welcomed with open arms, and ended up staying there for quite some time until he got back on his feet.
There are only two things you can do, throw away your Dads address and forget him, or take the bit in your teeth and get yourself round there.
Throw away his address, and you will never know what your Dad is like now.
He possibly had good reason to “abandon you”, the family argument is nothing to do with you.
I wish you the best of luck with whichever decision you make.
My Dad died at the age of 61 when I was 13, I never got to know him as my kids know me.
I will always regret not knowing my Dad better, even my oldest brother at the age of 23 was only just getting to know him.
