(Long Post I apologize in advance)

I recently posted a help discussion in a general sense about how I’ve been feeling with my current situation and partner but I feel like this should be a separate thing.

So the other night my partner and I spent some time together, this was the first time since they had established a relationship with their new partner. I was told they knew of me and they had talked about what the situation was and stuff. They also have a partner of their own already who the live with. Anyways R was heading home and I always ask that they let me know when they get home and such it’s not that far of a drive but I still worry. A hour goes by and I hear nothing so I start to panic a little and decided to try calling them and get no response, a few minutes later I get a call back saying that everything is okay and that someone (didn’t say who at the time) drank half a bottle of Hennessy and decided to roam the streets while drunk so R picked them up and took them home. I immediately thought it was their mother but was later told by R it was their new partner who was acting out because they were upset about R and I spending time together. I asked R if they struggle with addiction and they said yes to alcohol, weed and cigarettes. They assured me that this was just a relapse.

I explained how I felt about it and how in my own previous relationship my partner was a big alcoholic and abusive towards me, I said I don’t feel comfortable with them being in a situation that could potentially end up being like that. All R said was that they were sorry that this put me in a bad headspace. I felt like it was kinda dismissed at that point and didn’t know what else to say or do.

Am I in the wrong? Should I be worried?
