proposal tips?

um hi if you are gay married, do you have tips?

I am proposing very, very soon. I've talked to her family (they're supportive, which is wild because they were very homophobic when we started dating), she picked out her ring and keeps dropping hints about wanting to be afianced (so not a surprise), and I'm working with her friends to pull it off. I hired a photographer to surprise her

But like

The getting on one knee part? The confession of forever love? How'd that go? Ahhh???

I've never been as sure of anything as I am about her, it's just all the fuss that has me worried. I want to do it right, I want her to have the best expression of love she could ever hope for, I want her to know all the way to her bones that I am emphatically choosing her and will continue to choose her forever. But like, how do you say that?
