Input: (I live in Canada and marijuana here is legal, but please keep in mind that I dislike it due to personal reasons)

I had dated this girl for just over two months and on our first date I told her that I dislike drugs (including weed). I put it out there because I don't have the same views as everyone and I respect people enough to use drugs as they please, but I will not be in a relationship with someone who smokes weed frequently. 

She agreed and said that it wasn't something she liked either. 

We went out for a second date days after and I could smell marijuana on her as she was in my car. This confused me as it didn't make sense because she also said that she disliked weed and other drugs too. 

As we kept seeing each other her breath and clothes some days (not all the time) would smell like weed here and there, but not every single time I saw her. I didn't say anything because I didn't think it was my place and since I'm a little bit anxious I didn't want to offend her if my suspicions weren't right. 

A few days ago she asked me out of the blue "To what extent do you hate weed?" (I'm paraphrasing) so I answered and told her that I would not be in a relationship with someone who frequently used it. 
This is when she came clean and said she used to use a lot of different drugs but now she only smokes weed as a way to sleep, fight anxiety, feel happier and laugh. 

I was unhappy and felt disrespected that I was lied to. I asked her how frequently and I found out that it was a multi daily thing. I like this girl but as I said will not date someone who uses it frequently. 

She is never going to stop using it. "It's apart of me and I can't be happy without it" in her words, and I wasn't going to ask her to stop using it. 

I met with her tonight and suggested a breakup and she understood my reasons, we ended it on good terms but I can't help but feeling like an asshole. 

Am I?
