So, me and my bf have been dating a year and a half, he did pot for about half the time we were going out that I didn't know about. I got really pissed off at him for doing it and not telling me, I never wanted to date someone that does drugs. I found out about it in Feb. when I ran into him stoned, and he promised me he wouldn't do it again. From what I know he hasn't since then, but he's best friend is moving far away, and he is having a going away party, and bf told me about it and I was ok. Then last night he told me that there would be drugs there(marijuana) then I asked him if he was going to do it, and he said maybe. I got pissed off at him, then he said he wouldn't do it, and I didn't looked satisfied with that, so he said he promised he wouldn't do it. We didn't get much time to talk cause I had to leave right after, but I left him angry. I want to trust him that he won't do it, but I don't know if I can. Ever since I found out he did pot without telling me for so long, a part of my trust for him went away. I want him to go to he's friends party and have fun, but I know that night I'll be worried about what he's doing. I'm still angry that he even thought about doing it after he knew how upset I was about the whole drug thing. What should I do? Do I have a right to be upset about this? thanks.
