I've been with my boyfriend for a while now, and I love him, but from the beginning he's known about my family history with drugs, and because of how it screwed up my family, I don't associate with stoners. He told me he was the same way, his parents smoke weed and he said he didn't want to be like that. He said he didn't want to smoke, drink or do drugs. But then I get a text from my friend that's a screenshot of him talking about how high he is, then whoever he was talking to, I'm guessing, knew my stance on it and asked if I knew. Boyfriend said no, then the person said that he should tell me and to that my boyfriend said he was never going to tell me. And now I'm pissed and really hurt. Please help?

**UPDATE****

So he texted me and it was a misunderstanding. So it's alright now. Thanj y'all for your help.
