Dealing with women is really a mental thing, IMO.
Luckily for me I have a father that kept me ahead of the game. Some of the things I learned were pretty simple, even if it took me a while to really learn them.
1) Always, always, always observe someones actions. fukk whatever comes from their mouth, use your eyes and your ears. For example, I had a girl that I knew for about 10 years about a month ago. When I came over shawty crib, she had no condoms. That right there was a sign that she wanted to trap someone. I still hit, but I had a condom that I used. Later, she tried to tell me that she wanted a bf but I could not commit to her no matter how long I knew her for. I did not know her on that level, and we only fukked once. Shawty sent me screenshots of my instagram asking about bytches, called me asking me about bytches, etc. Plus I already knew that she was a whore and only cared about what she wanted. She said she couldn't fukk me anymore without catching feelings, I said fukk it, cool. The funny thing is she ended up telling me that she didn't want to be with anyone anymore, which was fine with me. A week later I got a call that she was pregnant. Basically nothing she said mattered, the fact that fukked me and I knew about her past actions were all I needed to get outta that.
2) Women only want what they can't have. This doesn't mean you can't open up at all. This means you never give anyone everything. However, you should never make yourself emotionally available. 9/10 women want this because it gives them power. Once you emotionally invest in someone it's like being a puppet and giving them your strings. It will not work to your advantage. Women will always flock to someone who doesn't give them that power.
3) Always assume there are other men. Especially when dealing with someone attractive. It will be virtually painless in the long run when you assume you aren't the only one, specifically because you will not care about certain things. Women will tell you all sorts of things to try convince you that there is no one else, when in reality whenever they don't pick up that call or answer that text, it is because they are talking to that person.
4) Be true to yourself. This goes hand in hand with #2. If someone wants you to do something that personally goes against what you believe, then don't do it. The only time this is acceptable is when someone will do the same for you. Trust me, there is not a lot of women out here that will sacrifice for you, unless they sacrifice that for everyone. 9/10 when you tell a female no, they will want to fight for it or find you more appealing since you aren't a pushover.
