Wtf is the point of lying?

3 months ago my SO stopped smoking. Great. He made that decision and I supported it for obvious reasons. But I did not ask him to stop. I would say for a bit now he hasn’t been boasting his milestones. That made me a bit suspicious because I feel like each should be celebrated.

I’ve suspected smelling it here and there. Thought I was just being paranoid. He would disappear outside sometimes. But last night I went after him very nonchalant. He claimed he was behind the shed to pee. But I smelled the smoke. And I don’t fucking get it. You want to smoke, fine. But why act like I’m oblivious and keep it from me? I hate lies!!
