We were both smokers before I was pregnant. We quit together when I found out in Sept 2017. Aside from being pregnant & now having a young DC - my grandfather died of lung cancer, and DP's dad died of the same just last year. So we are agreed that smoking is terrible.
I have since caved in a few times & had a cigarette when on nights out, thankfully it never amounted anything but nonetheless I told DP as honesty/transparency is important to me.
In recent weeks my DP has been smoking behind my back. I've no idea how much, but I have caught him out 3x and each time discussed how important it is to me that he is honest with me, but he has done it again.
The first time my friend mentioned that he'd been smoking with her partner, she thought I knew. I discussed with him that I'd prefer if he told me this kind of thing & he agreed. Then I caught him smoking in the garden after he thought I'd gone to bed. He was apologetic and swore it was the only/last time. But yesterday I saw that he'd cut a stick of filters down to make it look like none had gone. Yet he still claims he's not addicted.
I don't know if I'm making a mountain out of a molehill. He can smoke, he's a grown adult. It's a shame & I don't want DS around it but I'm not going to control him. However I can't understand the dishonesty? He's lied about other things in the past too, I don't feel as though I can trust his word.
Advice please?
