Dream of

I am walking down the street and this guy comes up to me and starts talking to me. I talk with him and and we walk into a restaurant. My ex is in the restaurant and he goes up to her. He starts talking to her and out of undying I go up to him grab him by the shirt and tell him that if he talks looks or touches her that I will kill him. He then extends his arm and strokes her stomach. I grab him by the throat throw him onto the ground and proceed to pummel him. Then after about a minute he gets up and runs away. I start to chase after him but my ex tells me it isn't worth it.
