A little background. My SO and I have been together for 4.5 yrs now. When we first started dating, we both knew each others dislikes about the other gender in general and what we were looking for at the time. She has known from the beginning that I did not like girls with tattoo's, even though she had just gotten one when we met, I let that one slide because it is 1sq.in. in size and not able to be seen in public. She also knew I was not big on drinking(to get drunk was a def. no, social drinking I would have like 1 or 2 the whole night), and a very big disgusting NO to girls to smoke. That is a very big turn off to me. So, she went out to her friends bacheloret(sp?) party this last friday, which I was fine with. But it came to my attention that she smoked that night(within the same night). (I'm guessing the influence was her dad used to smoke, her mom smokes every now and then and is trying to quit, her older sister smokes socially, and she was with a bunch of other girls that smoke) I guess she did it because she was with her sister and a bunch of other girls who were smoking that night. This last saturday (the next day) I go to see her, and she does not tell me that she smoked, while I was trying to get it out of her on the way to my house. bassically the convo was like this: Me: How was the party last night? Her: yada yada Me: Arent those clubs in downtown? Her: yes. Me: thats cool, atleast ya'll didnt have to deal with smokers. (in Houston, smoking is banned from bars, and clubs) Her: yeah, I hate it when you go to places and your clothes and hair end up smelling like smoke. Me: yeah me too, I hate it when girls smoke, it is nasty, you should tell your older sister to stop. Her: yeah, yada, yada. So I didn't get it out then, but later on in the day, we were laying down, and I started another convo that went like this. Me: Your hair smells funny (we were in the spooning pos.) Her: funny? like what? Me: like, I'm not sure, smells like cigarettes or something. Her: oh, it was probably from the girls smoking. Me: oh, I thought they couldn't smoke at the clubs? Her: they couldn't, but they were smoking outside waiting on the cars, and at the girls house, etc. Me: oh, well your hair smells gross. Her: sorry... yada, yada So she never admitted to it, even when I directly was trying to get her to confess to it. She knows I hate it, and yet still does it, and then doesn't even want to tell me. I know for a %100 fact that she smoked. So my question, Is it right for me to bring it up, and be mad about it? This is one of those things where I will not tolerate a SO that smokes, and I do not want her to get into the habit of doing it socially cause then we will deff. not be together. And at the same time, her not telling me is making me feel like I can not trust her. Even thought we have been together for 4.5 years, we have had problems in the past and this is just kinda like making it seem like the problems are not worth it. What do you guys think? (sorry for the long post) Cliffs: My long time SO went out, and starting smoking, knowing full well I HATE girls who smoke, and did not tell me about it, although I know she did. What should I do when I bring it up?
