Dream About Abusive Ex And Setting Boundaries

I was back together with my abusive ex. It seems like I gave him a 2nd chance or something. I was living inside an apartment that was familiar to my childhood home. My friends and siblings was there. I specifically remembered seeing my older sister Jenny and my estranged brother in the dream. I don't remember seeing my eldest sister but I knew she was around. My ex was playing video games and he told me to get him a coke. Something he often did during our relationship, order me around. But this time in the dream I asked him to rephrased his request as a question and to add please. Because I was practicing boundaries on how he should speak to me. He rephrased it but deliberately didn't add please. I told him I would not get him the soda until he asked me the way I would like it be asked. I went back to my friends and family letting them know what he did which was something he often did during the relationship. I wanted them to see the abuse I've experienced before. They took my back and supported me in putting that boundary up. My ex did not budge he continued playing video games and instead of rephrasing the question went to get his own coke. For some reason are started to feel physically insecure to be in the same space as if I was unsure if the issue was going to escalate so I decided to leave. I ended up in the subway/train station with friends nearby all supporting me. My ex was at the station to attempting to leave too but I knew he was only there because I was there too. I was trying to dodge him and I found one of my friends I hugged them and somehow it was like we were able to hear him from some sort of comms radio where he was at and my friends helped me nor encounter in the subway/train station while I was there and I was able to dodge him with the help of my friend. I remember feeling validated by my friend and family being there to experience and see an abusive act I often had to deal with throughout the relationship especially one of the most covert type of abuse, which is verbal and emotional abuse that aren't often taken as seriously as physical and sexual abuse though I experienced those in the relationship as well.
