Extreme amount of waswasah please help

Asalamualaikum may Allah reward you have a hypothetical question 1)Hypothetically if a man has intention of “talaq” keeps his mouth closed and tries to breathe the word through his nose, for example ‘talaq”’, without pronouncing it with his tongue or mouth, does that count as “talaq” Woukd that do anything to the marriage.? For example if u close ur mouth and Try to breathe so ur breathing out like the word "hello” as u breathe through ur nose as your Tryna say that through breathing 2) If a man only says the first letter of the word ‘talaq’ (for example just ‘t’) and stops does that do anything 3) I didn’t do any of these and suffer form extreme waswasah how can I combat waswasah. 4)also as I was typing in the point above how “ I didn’t do any of these “ I paused after typing the “I did” before adding the rest cause of waswasah.I then cut it all then typed it all again. does the pause do anything. I have no intention Jazakallah
