Search Results: being fake in a relationship

I have two dilemmas. The first one involving a fake person and the other involving an obnoxious one.

The first girl happens to be my second cousin (don't know how significant that is) and to keep it short I warned her about crappy guys she was hanging out with and she told them what I said and they all lashed out at me. She acts like we're cool now and always talks about me being her favorite cousin, only friend, etc. when she hasn't even apologized for the problem she put me in. Part of me really wants to confront her actions and the other part of me suggests to be nice to her and act like everything is cool. I don't care about my relationship with her I just want to pick the way that makes her look more fake. She already knows that I found out she told the sketchy guys what I said about them, but it comes down to if it's worth confronting her or not.

The second girl is just a bitch ex who wants to see me at my lowest. I finally found a girl that I might date and the moment I start talking about her she says my potential girlfriend has a weird name (she knows we are seeing each other). She does similar stuff like this whenever I see her and I would avoid her and the first girl I talked about but my family is good friends with both of them so I spend a lot of time with them. The question here is if it is fair game to bring up all the shady stuff she's done in the past? She sent nudes to a guy that had a girlfriend while she had a boyfriend as well as attempting to hook up with a guy that has a girlfriend. If she pulls a bitch move with me like making fun of my potential girlfriend's name, would it make her look worse if I play it off cool or bring up all the shitty stuff she's done in her past?

At this point I have kept my cool with both of them.

Features of a sociopath:

1.
Many women will flirt and put on the girly act to gain your trust.

2.
Think about how many girls these days take selfies constantly and stage photos in public areas to appear their having fun.

3.
Women tend to lie about a lot of things from very small as giving a guy a fake number, to saying they don't have a boyfriend, even sexual partner count and their persona are often fabricated to give appearance of what their trying to project to that person.

4.
Women actual excel this. This has been supported by research.

5.
Many women can say they love you but as soon someone better comes along you mean nothing to them. Women have actually been shown to abandon their male partner if he loses his job very often.

6.
Women often rarely feel sorry about their actions. They will feel sad about the consequences if they do exist but never really about actually doing the act.

7.
Many men today say its a lot easier to get women to fuck you these days than actually form a bonding relationship.

8.
Relates back with 2. and social media. Many women have their phone on them religiously and are constantly on social media looking for likes and validation.

9.
We see evidence of this on GAG where male concerns are often scoffed at as being not important or ridiculed by women. We can even see demonstration of this with feminism which was said to be about "equality". Yet, feminist have not given a damn about male problems in society and actually made it worse.

10.
We see good example of women's impulsive nature when we look at divorces. Many women go by their feeling and do not consider the effect that such an act will have on their husband, and children (if they have any). This ties back into the lack of empathy.
