I hope this is in the right place for some advice. My dad seems to be withdrawing himself from everybody. What I am looking for is some advice on how I can help him or maybe how I think about this.
To cut a long story short, he and my mum married in their early 20's and they had nearly thirty years together. She died just before her 50th birthday. This was 14 years ago. He threw himself into his work and us (brother, sister and me). We had left home, but obviously were coming back frequently to grieve as a family and support each other. Three years ago dad met someone and it got serious. We were happy because he was genuinely happy. The relationship broke down and I believe she became too needy and demanding (not his ideal woman and mum was never like that). Eventually he admitted to me but not my siblings that she stole a lot of his money. He is pilanthopic and gives money away. He has always done this. Her actions have changed him. This year he has become more distant. He was never on social media, but now he is. When he had the business he had teams of people to help him, but now I do it setting up his accounts and internet banking and security. I transfer money for him and pay bills. He spends his days listening to music (the same songs) and he has the family pictures out, spread on his office spaces. It is like he is going back in time. He does not go out and has no connection with his old friends. Emails they send go unanswered. He regularly transfers money to help people he does not know. It is his money and these are not big sums in his overall picture, but he just sends money to help randoms. He goes very private, back into the past and mum. His life is slipping away and he was, until this other relationship, full of life. That ended two years ago and he seemed to get over it, but now he has gone into this odd place and no longer feels like dad. I am no relationship expert. Just trying to understand what is going on in his mind and how I can help him.
