Is this right?

So me and my boyfriend of near two years got on a break. He asked for the break cause he didn’t know if he needed time away from me or not being with me. He said he felt uninterested but the week passed and he wanted to stay with me. I of course gave him the chance but with some conditions. One of which is not to talk about being an alcoholic. I don’t like the idea of that like for me that’s a turnoff. Also I never see him talking about a future where he will go get a good career but he can see himself being a drunk. We were in a call and he started talking about that and I was like haha stop joking and he said he wasn’t.. idk how to feel about that. I just felt like I needed to vent😅
