So there's the girl. You've known her for a while, and you've always been interested in her. Doesn't matter how you know her; could be work. Maybe a class. Maybe she goes to your gym and you chit chat while you're there.
So this girl keeps telling you stories about all these shitty guys she keeps dating. Guys who manipulate her emotionally. Guys who fuck her and then don't call her back. Sometimes even guys who hit her.
Your natural response is probably going to feel like you need to protect her from this injustice - from whatever pain she's feeling emotionally or otherwise. If only she could see what it's like to date a good guy like you. You're going to want to save her. Especially if she has a kid.
What you're encountering in this moment is a woman of poor decision making skills who allows her life to spin out of control. In the 21st century in modern countries, especially those in Europe and the West, woman have more rights and freedoms than they ever have in history. They are also afforded protections under law that allow them to financially destroy their spouses through alimony and outlandish child support. Broken, damaged women with emotional baggage and sometimes children are not an RP man's idea of dating material.
The risks in dating these types of women are everywhere. First of all, why would you ever want to date someone who can't keep their own life in check? If she's getting evicted from her place and "needs a place to stay for a while", what does that tell you about her ability to manage her own finances? What happens when she needs to borrow money from you? If she's got a kid, how long before you "take on a fatherly role" as the state would put it, and she can hit you up for child support? What happens when you realize she was full of shit about all her stories of being abused and is actually bat-shit crazy and starts accusing you?
Don't put yourself in these types of situations. Women who are like this do not want to be saved. They want to continue behaving like children and riding the carousel. They are not yet emotionally mature enough to be in a relationship that can succeed. And if they have a kid, you shouldn't be responsible for it. She should.
It's been said before that TRP is the radical notion that women are people. So don't save them from their mistakes. If you wouldn't do it for your friend, don't do it for her just because she has a vagina. Afterall, that would be sexist.
