I love with my girlfriend. She's in the process of selling her house. A few months back, a family rented the house next door. They've been horrible. Very rude, loud, ton of people. He owns a construction company and always parks his big work truck in the grass in front of my girlfriend's house. Grass in front of the house is empty,  as is his driveway.

Last night around 9:30, she is going to get her daughter. He is outside so she politely asks him to move the truck. He EXPLODES. F-bombs everywhere. Approaches her in a threatening manner. I hear this and go outside. He and I are about the same size. I speak in an authoritative way to let him know, hey, you're not in control here. Relax. He then goes between apologizing, threatening, m'fing me. Etc. We argue. My girlfriend gets me into the house.........and proceeds to yell at me. Saying ITAH and I'm embarrassing her. That pisses me off because I know if I stayed inside, I'd get yelled at for not having her back. 

I cool down. She again tries to leave to get her daughter. I go to go for a drive. When I do. I see her. Our other neighbor and the ass hole neigh or yelling. The other neighbor is a great guy. 67. Always looks out for her and her daughter. I get out of my car but just stand back. When it looks like the AH neighbor is about to attack, I then get in the middle and he backs off. 

Police come,( he called them saying he felt threatened by me but as soon as he hung up he said I'm lucky the police were coming because he was going to beat myass lol), he moves his truck, blah, blah, blah......but the rest is not important. I'm asking, am I the asshole? I'm still upset at her comments she made to me after I defended her. I'm not kidding when I say the guy was definitely trying to intimidate her verbally and physically  before I stepped in.
