<human>: Can you condense the text into a few key points?

My boyfriend and I met in September 2011 during the first week of Canadian college. We hit it off pretty instantly and began dating in the beginning of October. I knew that he smoked weed and I did too occasionally, so it wasn't a big deal really. He even cut down the amount he smoked a lot because I smoked very little actually. We were head over heels in love with each other, just absolutely crazy. We made each other so, so happy. 

In the beginning of May, I moved in with him and his family for the summer to work. I'm from a small town with little to no job opportunities and he's from a city super close to Toronto. So although we'd only been dating a little over 6 months at this point, moving in was necessary for me to find work. We would've missed each other terribly as well so the move just felt natural. 

Not long after I moved in, he had to do some shitty car repairs that cost $3,000. He said that he wanted to start selling weed. Smoking is one thing, but selling is another. I told him I didn't really like the idea of it, but he said it would just be temporary. Everything else was still great, so I decided I could just grit my teeth for the time being until he was done. But every time he picks up, he picks up more and more. One time he was scaling a decent amount and I told him he needs to be careful, and he replies "I don't think about it so don't worry". Uh... yeah I'm worried. 

I thought I could be okay with it because I love him so much. But every time some random number or some guy texts him to pick up, I get angrier and angrier. I'm starting to become resentful and it's starting to show by my increasing frequent irritable moods. I want to talk to him but I don't know what to say. Breaking up is NOT an immediate go-to option because this is our first serious problem and I need to attempt to work through it with him first.
<bot>: My boyfriend sells weed and it pisses me off and I just can't help it, how can I talk to him about it?
