A bit of backstory: I (16f) started smoking about a year and a half ago after an incident with an ex boyfriend left me with some pretty bad anxiety, especially at school. I picked up smoking as a coping mechanism, but dropped it for a while in favor of vaping. When I dated my current boyfriend for the first time (May-Aug last year), I wasn't smoking very often because I was in a pretty good place, mentally. I picked it up again in September because stress and it's way cheaper to buy a pack of smokes than it is to buy a bottle of vape juice. 

We got back together in January of 2019 and I can tell he wants me to quit, even if he won't say it to my face. I don't really smoke when it's just him and I, but he still knows I do it. I've been playing dumb as much as possible but I know he wants me to quit, but I don't want to have to argue it with him or try to convince him why I smoke, he knows that I've been through a fair bit of trauma and that school is a big source of anxiety for me. I go through about half a pack on a bad day, so my habit isn't nearly as substantial as some of the people I know.

Recently, I filled my friend in on the situation, and he told me that I'm being a bitch for continuing to smoke and not stopping out of courtesy for my boyfriend, so I'm asking the good people of reddit to help me settle this one.

Am I the Asshole for playing dumb about the situation?
