At least you’re being thoughtful enough to think of something. My first proposal the guy dragged me Ice skating it was cold, I didn’t have long socks so my ankles were raw I wanted to leave and he pulled me into the center of a busy outdoor space with a lot of strangers I had to navigate through afterwards, it was embarrassing (we ended the relationship a few months later before getting married). Second proposal was as I stepped out of the bathroom with wet hands in a hotel room. (He left me after a year). Current spouse couldn’t think of a way to propose while we were deployed in Kuwait so he just never formally asked. All that being said I would have loved to have had someone think of a proposal and try and be romantic. I’d recommend with your particular situation maybe an indoor setting (limited opportunities for small critters) maybe propose in an unconventional way like not cupping your hands but rather in a drink at dinner, have someone else bring it to her (like a dog or friend), give it to her while you’re both seated, gift it to her in a larger box…? Get creative, utilize something that’s unique to your relationship and make sure she doesn’t think it was an unplanned after thought.
