Sorry to hear that soupie. You could have scolded him by saying he gave up on you some 37 years ago but again your the bigger man. It’s a credit to you and your young son. I think your relationship with the old guy may have found it’s level even if it’s not great, any breakdown won’t be your doing. There wouldn’t be a soul on this forum that would judge you for whatever path you take. If u told the suspicious old buggar to beat it, I for one would think that’s fair enough. Keep some air in your tyres, your a good man.
