PLEASE don't take it as rejection. This is just the way your dad is. It hurts me to hear you say that......
It sounds like your dad hasn't had the easiest life. and it sounds like he loves you but gets defensive any time you talk about HIM. *sigh*
I wish I had something to say. I just don't. It hurts me that he treats you this way. It's NOT your fault! It DOES hurt...but just realize it's not YOU...it's HIM with the problem.
Unfortunately when people harm themselves...they take those that care about them along for the ride.
Can you speak to your mom (mum?) about this/ What's er role?
*big hugs* foryou...don't give up! Maybe ne day things will change...praing for you With love, Ruchie
