Dream About Ex And Coworker Makeout

I had a dream I brought my ex around this coworker who is known to sleep around. When I introduced them they got real close and then started staring into each other eyes and then started making out . I jumped right up and started beating the crap out of my coworker. When I left, I knew I was going home with my ex and specifically remember telling myself “you are still going to sleep with him even tho you know he would have just slept with her if you hadn’t jumped in.”
