Yes like I said, I knew that by marrying my K1 visa would become inactive. So in my head I thought I was "withdrawing" and starting a new application. But I looked back at the letter I sent, it never uses the word withdrawal.
" I filed an I-129F form on _________ (Case Number: _________). When we first submitted our application, we thought that would be able to be reunited and married within a year. However, due to processing delays and longer wait times my partner and I decided that it would be best for our situation and mental health to get married.____________________. So, I hope that you will consider our new I-130 petition and allow my husband and I to be reunited promptly so that________________________________ "
that was what my letter actually said. Im sorry I used the word "withdrawal" but it didn't use that word in the letter I sent. Just assumed that by letting them know I was married they would "withdraw" the application and turn it inactive as I am very much aware that by marrying my K1 visa was no longer applicable. However, the K1 has remained and still is currently active for several months now since I sent the letter. I called USCIS today for that whole reason, knowing that a K1 shouldnt be active after marriage.
