I am sorry you are feeling this way. One thing I notice is that you are so set on the idea that a potential mate would just want your money. Do you really have that much money? It doesn't sound like it to me. Sounds like you are comfortable and may be well off when you inherit pensions but to me it doesn't sound like you are "rich". I wouldn't automatically assume you would only find gold diggers interested in you. And even if you are super rich that doesn't mean everyone is after your money. Also plenty of women have married rich and famous people and agreeed to sign a prenup, so just because you want that doesn't mean you won't find someone.

I know it is hard but you have to try to tame your attitude. It may be a long time before your mom passes away. I have grandparents in their 80s. I always used to worry about them passing away but instead I lost both my parents before them. Just goes to show you life isn't always what you expect.

Try not to focus on finding a "replacement for your mother". If you're looking for companionship and want to date then you should do that for the sake of doing it. Don't go out looking for someone to replace her because that is impossible.

I am awful at this too- but find hobbies if you know you won't be working. Or volunteer if you can. Keep yourself busy. And plenty of women won't care that you don't have to work to make money, you say some people are mad about that but I can tell you there are people who won't care.

Good luck
