Unemotional detached partners, usually already have a relationship with a demon within themselves.
The irony of this situation though is this. These are the guys if they lift themselves out of the mess, have the highest chance of being the authentic and real men that women really and truly desire and want.
Cats are very very fincky, and if the cat loves him that will speak volumes of how he will treat you once his stoic walls are down.
The thing is though, it isn't your job and you shouldn't have to spend more emotional energy out of it then saying ... "dude" not sexy or desirable. Love you care, don't love the downer experience.
