My Dad has just left after visiting for a week (stays nearby, not in my home) and first the first time ever I'm really relieved. And that makes me so, so sad. I love him more than anything - he's my only really close relative, but the relentless negativity is soul crushing. He complains and grumbles about absolutely everything (yet if someone asked him if he'd had a good time on his visit, he'd tell them it was great!), and I feel like I'm constantly being reminded that I haven't achieved what he'd have wanted for me in my career (I'm a freelancer, relatively low earning but extremely happy and can work flexibly around my hobbies). It's almost like this grumpy old man persona that used to be a joke has overtaken his entire personality.
I want so much for us to have a close and happy relationship and be kind to eachother but I'm starting to dislike spending time with him.
What do I do?
