I would not send that letter, nor would I rush into marriage.
For a start, the letter is kinda strange (USCIS doesn't care that you like to dance and/or are good at dancing, or that 'Jeremy' likes gaming, and while the disappearing tenant is a curious little subplot, it's not relevant to your immigration journey).
And the timing is very quick. You married in 2021 and, in 2023, you're already divorcing and have a new partner lined up. I would focus on the divorce. File with the divorce waiver. You and Jeremy have a wonderful life ahead, by the sounds of it. I would not mess it up by acting in haste. I wish you good luck!
