Dream about brutally beating cheating husband, and wearing a captain america costume? What does it mean?

So I’m at a touristy type/barber shop with my girlfriend. We are both getting our hair done and my girlfriend says that she heard one of the girls that worked at the barber shop performed oral sex on my partner. (In real life, my partner cheated on me once before we got married and in waking life I am not worried that he will do it again. I trust him.) Back to the dream. I’m mortified and unbelievably upset. I try to call him but his number isn’t in my phone. So I try to punch in his number, I remember seeing the cover on my phone very visibly as I try to punch in his number over and over again, but somehow the incorrect buttons are pushed. I cant seem to type in the right numbers. I’m getting very irritated by this and choose to go find him on my own. i end up finding him and start questioning him about said girl. I reckon I questioned him something like “Have you been hooking up with other women?” or something. He’s avoiding the question and being catty with me, but he finally admits to it. I start beating him in this alley/parking lot type thing. I’m hitting him over and over again, this unbearable rage comes over me. I beat him for a long time when finally he says “okay, okay…” And I stop. I throw my ring at him. The scene changes and I’m walking up stairs to my mom, she questions if I’m okay and I say I’m fine, even though I’m crying. The scene changes again and we’re at the control station. I’m with a very close friend. My partner is drunk and being obnoxious.
For some reason he was responsible for us, and since he’s drunk he can’t drive us home. (I dont know why we were at the control station). The cops are mission people to come get us. I say I can take care of myself, and I run away with my girl friend. I remember telling the cops that we weren’t with my partner and we can take care off ourselves. I was still livid with him about the cheating thing. We’re running down another alley that resembles some of the alleys of the town I grew up in. My partner is following us. For some reason my girlfriend and I are both in a Captain America costume. My partner catches up and my girlfriend disappears. I’m crying still, but allow my partner to place his arm around me. I feel safe. He keeps trying to pinch my butt but I tell him to stop because I’m crying. I feel overwhelmed with like and rage. We hear the cops as we’re walking up more stairs to get out of the alley, and we try to hide behind a bush, but I’m in a Captain America costume so the cop sees us. Then I wake up.\

Please help me figure this out! I had this dream only a few days after
we got married. Both my partner and I still wonder what it might mean. He used to have a drinking problem which is why he cheated on me.
