Like... as an example the guy who makes me feel safest is my best friend who's like the brother I never had. Even though he could wipe the floor with most other guys and owns a gun, he's a really smart and classy guy who has a way with words. He can verbally tear down a person, without even insulting them, he'll just make them feel bad about what they did, and that's probably what he would have done if he saw some other guy hit on his girl. If I have a problem he's there in 5 minutes, he's always helped me with a lot of stuff, he's generally there for me and just the thought of him makes me feel safe. I just know I can call him for anything, if I had to bury a body his would be the first number I'd dial.
I guess I generally feel safe with a guy that I know is smart enough to get out of any situation rather than someone who's gonna solve everything with violence. My ex boyfriend was like that and honestly it didn't make me feel safe one of the reasons being I always thought one day he'd pick a fight bigger than he can handle and potentially get both of us hurt.
