AIO for being upset after finding out my husband was smoking again?

Reposting as my previous one was removed:

This sounds ridiculous now that I’m writing this. My husband has since quit smoking ever since we got married last year. I know how hard it is to quit and I applaud him for this. He knows my aversion to smoking and how I hated the smell of it. I always had heightened sense of smell, which is both good and pretty annoying.

The past few months, I noticed that whenever my husband comes home from work, he smell like cigarette. I asked him if he smoked, it’s just out of curiosity, he said he did not, but it’s probably the smell of cigarettes from people outside sticking on to his shirt. I put it out of my mind as it’s a reasonable answer considering where he works smoking is a way for people to relieve stress. But this happened few more times and he was adamant that he’s not smoking. I told him, it’s okay if he smokes at least once as I know how hard it is to quit plus the stress in his work, and if he ever smokes he should tell me. He insisted that he did not smoke and if he will, he promised to tell me.

Then one day, I found a lighter in his work bag, this happened few more times and I already feel like I know the answer. I casually asked him but he just says he steals this from co-worker as inside jokes. I again dismiss it although It’s already bugging me. I just trusted he would come clean to me. I told him again, it’s okay with me, he can tell me if he smokes again and I won’t be mad as long as he tells me. But he still denies smoking.

Then the other day, I found an unused cigarette on his pocket while I was about to do laundry. I asked him about it, he said that he bought it and thought about smoking but decided not to, hence it being unused. I was skeptical of his answer but I still gave him the benefit of the doubt. I found couple more of lighter in his bag after and I didn’t mention it to him after, I just removed it from his bag and placed it somewhere he can see so he knows I saw the lighter. I already have a feeling he wasn’t being honest and don’t know how to tell me so I thought this way he’ll fess up, still nothing happened.

Then came today, we had a minor misunderstanding (which was already resolved) and he went out to get something from the convenience store. When he came back he brought a Pineapple juice (my favorite) as a peace offering (He do this whenever we have a minor disagreement) and hugged and kissed me. And then I smelled it then I tasted it, if you don’t like cigarettes yk what I mean. I asked him, did you smoke today? It was casual not accusatory. He was silent for a moment and fidgeted before saying “yes”. I don’t know how to respond to this. And then I asked him if it’s the reason he went out, he said yes and that he’s been smoking for a while and wasn’t able to quit. I asked him if he’d been smoking all those times I caught the lighter and sniff him he said yes.

I already have a feeling that he’s been smoking, but I genuinely thought he would tell me about it as it was what we agreed upon. And sneaking like this despite giving him all those hints that I know feels like breaking my trust. He said he couldn’t tell me because to hime it feels like a heavy subject and he’s been traumatized by his parent’s reaction towards him smoking. Idk, this feels superficial but I do feel hurt about this. And I gave him plenty of ways to fess up. I really feel hurt by this and it may sound corny to others but I did cry too (not in front of him ofc). Please be kind, AIO?

ETA: My husband has Asthma so his quitting wasn’t because I asked him to, but purely medical. Before we got married I understand the thing my nose is going to deal with in terms of him smoking and when we’re still dating he doesn’t smoke with me there, and I respect that about him. He did tried a vape (I believe it was Icos? Idk) but eventually stopped it for good. I am not controlling his smoking, as I know quitting is hard especially as he is surrounded by people who smoke too, I just wanted him to tell me.
