My Dad left when I was 17 he had been living a double life for 6 years. After he left I had very limited contact with him however my sister did as they both worked close to each other and would meet up.
My sister has maintained contact with him and his now wife but I haven't, I have only spoken/seen him around 10 times in the past 28 years.
My dad has recently been unwell and is currently in hospital, my sister has been visiting and keeps asking if I am going to be visiting him, asking me to phone the hospital to find out how he is. I have told her I am not sure if I want to but she keeps pestering. I don't live near to where they live I would have to travel up for a weekend.
I am finding it all quite hard to deal with, I haven't told anyone this.
