I hid my nicotine addiction behind my partner's back (I relapsed) for half a year before finally telling her.
It started off as "I didn't actually relapse, this is just a bump in the road"
Then I started lying to myself, saying this was the last time I'm buying zyns at the gas station, rinse and repeat for months.
Got to the point where I became too embarrassed to say I relapsed, had a zyn in my mouth at all times, felt like I was having withdrawals even if I had one in my mouth.
Finally admitted to it after she suspected something, felt really ashamed, but it was like a weight was off my chest.
Quit shortly after, having someone supporting you can really give that final push to quit
