My partner advertised herself as being more of a nature girl than she actually was. She told me later that she was just trying to impress me. While that was disappointing at first, there's so many things we have in common that it wasn't an issue. And it's honestly better now because we take things at her pace and she has a better time, like for instance, we spend an hour at a nature trail and then go to brunch as opposed to a multi-day camping trip. It's very nice.
Me feeling like I needed whoever I'm with to go camping with me is something I realized I could let go, just like OP said, because I can find other people in my life to do those things with. I think sometimes we come out stronger by letting go of our expectations.
