I'm mid-30s and have recently started a relationship with a lovely man who is a few years older, and it's going very well. We both seem equally keen on each other, and everything I learn about him makes me like him even more. We seem to have the same values and goals in life (e.g. regarding family), we have lots to talk about, and we are always making each other laugh. It all feels very positive, and I am optimistic for the future after thinking for a long time that I wouldn't find someone who makes me feel like this. Both of us have similar long-term relationship history, and neither of us has kids.
The thing I'm a little nervous about is him finding out how well-off I am compared to him, and whether that will change anything in the way he interacts with me. He works in a creative field and earns well for that sector (and is very good at what he does), but it simply doesn't have a very high ceiling. On the other hand, I work in a field that happened to become incredibly lucrative a few years ago, and so I've managed to accumulate savings that I would never have thought possible. I don't care in the slightest about the wealth disparity - I feel lucky that my wealth gives me more freedom to live the life I want, and to share that freedom with the person I love.
It wouldn't necessarily be obvious, as I haven't really inflated my lifestyle much. Except for the fact that I live in a large detached family house in a nice part of London, on my own. (I did actually buy it with a previous partner with thoughts of the future, but we broke up and I was lucky enough to be able to buy him out, as I really love the house.) As it stands, I have only been to his place, but we're getting to the point where we would both like to start spending more time together, and it would make more sense logistically if we spent some nights at mine too. I feel quite nervous, because I don't know if he will have some instinctive reaction when he sees where I live. I also feel a bit embarrassed about it, because it is a little ridiculous me living there on my own. He is someone who clearly likes taking care of me - he does a lot of small thoughtful gestures, and he always wants to pick up the bill when e.g. we eat out (though I have made sure to even it out a bit), and I really don't want him to feel that my financial position changes the importance of his gestures/contributions. I really like feeling looked after.
I might be overthinking this, but I know money can affect how people view things, and I really don't want to approach this wrong and potentially change our relationship. Should I say something to him before he sees the place? Should I make a joke of it? I want to avoid over-explaining, or saying things based on false presumptions that may not even apply. But I'm just really nervous about him seeing where I live and suddenly realising there is a big wealth disparity, and it potentially changing how he sees me or our relationship.
