If you are very young (25 or under) it could certainly shift your thinking. I took up psychedelics in my 40s, and who you are is generally a lot more settled then.

I’ve been married for lets see, 28 years - and my opinion there is nothing better in this world than a good woman, nothing. So in your shoes I’d shrug it off, express that well, you really would like to partake and revisit every so often.

Personal space is also vitally important in a relationship too, so you may decide its an activity that you ride solo with and don’t feel the need to share much of with your partner. I’m this way - I don’t hide it, but it isn’t something I discuss with her any more than sailing or rowing or any other hobby thats in my wheelhouse. I think that sort of practical approach is common in longer term relationships - you both have interests the other isn’t into, no biggie.

But I’d either get to the point in the relationship that that isn’t dramatic or anxiety inducing or persuade her, one or the other. Its not worth ending a relationship over, but you don’t want it to be a dramatic backdrop either.
