This is an incomplete list in absolutely no order of the types of girls to avoid when looking for a relationship.
Girls who claim to be "crazy" , but do not see a psychiatrist or take meds
People who refuse treatment don't belive that they have a mental disorder, if a girl brags or blames her rage on a psychiatric disorder its due to her being immature and seeking attention. If a girl has a legitimate disorder she is find to date, just make sure you understand her condition before hand.
Girls who drink to much
There is nothing wrong with a girl that likes to have fun, but girls who drink/drug every chance they get will leave you the minute something (or someone) else seems more fun.
Self proclaimed "Gamer Girls"
This goes for girls that are overly enthusiastic about anything that is typically a guy thing especially if they chose to define themselves by it. They are doing this for no other reason than to attract male attention, because they know that their personality is shit. Do note there is a big difference between "Gamer Girls" and girls who game.
Girls in a completely different stage of their life than you
Its better to choose to date someone who is in a similar stage of their life than you, if not , you will both have to make a lot of sacrifices to make things work, and if it doesn't work out in the end it was all for nothing.
Girls who hook up
You know who I am talking about and you know why you shouldn't date them. As hard as it is to resist you have to keep it in your head, If it is this easy for you, it is this easy for everyone else.
