Before a chick comes to my place, and these come from experience, here are 3 things I look out for:
1. Extreme behavior changes after drinking alcohol. I'm talking bi-polar like craziness.
And it might not be the alcohol in some cases, but just that she really is bi-polar. Met some chicks that changed personalities like it was an Exorcist movie.
One chick in particular that stood out, was actually fantastic at sex. She could deep throat and squirt. When she got drunk, she loved anal sex. Would demand it. She was good looking too, so even though she was like a bad alcoholic drunk, tried to keep her around.
After 1AM in the morning, and out of the blue, she decides to show up at my place. No calls or email, just knocking on the door, and demanding sex. Very luckily, my other girl canceled meeting that night.
First time, kind of border line fun, but told her not to pull that shit any more. Did she listen? Hell no! She does it again, and was driving drunk. Like at 2AM. Knocking loudly on the door, accusing me of having another woman in my place, screaming, etc... Let her in, to stop her from waking the neighborhood, she starts trying to tear up my apartment.
Had to reluctantly cut her off and forbid her out of control crazy butt from coming over. And it hurt too, cause the sex was good.
2. Jealousy fits & too sucpicious
Like the above, but without the alcohol added. Had some extremely insecure Japanese girlfriends go way overboard with this. Like I'm just looking in a general direction, but they accuse me of looking at other women. Trying to look at my phone, asking me questions like she is a police inspector, etc...
She shows signs like that and you bring her to your place, you can be unleashing the demon. Chick running through your stuff like a cop or on an Easter egg hunt.
You can trick question ask her about her previous relationships. If she claims to have done and caught boyfriends in the past by doing that bullshit, it's likely she will try it on you. I mark her butt, "For Hotel Use Only."
3. Controlling & Extreme Manipulation Attempts
Related to the above. These can be deranged crazy chicks that think they are going to boss around a grown man. Like barking out orders to you, as if she's your boss or mother. Often they did this craziness on some weak guy before and testing if they can get away with it on you. It can also be the first step in her police warden and jealousy fit act. Usually I dump these type women after 2 or 3 hotel sex encounters. Definitely recommend not ever taking such women back to your place, because the DRAMA is sure to follow her in.
If a chick acts crazy or nutty, label her- "For Hotel Or Outside Sex Only". If you suspect something is off about her, better safe than sorry and regretting you brought her to your home.
