OK. Here is the truth. He is not that into you. Women are genetically disposed to only be attracted to men that are generally 2 points higher in Sexual Market Value than they are. Women are predisposed not to be attracted to those men that would commit to them. They want better men than the men that like them. Now, that is no big deal when you are something like a 4. There are still a lot of men that are a 6 out there. But if you are a 6 or a 7 and you are chasing a male 8 or 9, the normal distribution, the bell curve, mandates that there are not many of them and other women want them also. So most of those women with a SMV of 6 and 7 are chasing the few 8 and 9 men that are out there. He is not phobic to commit. He is foolish to commit because he has multiple options. And if you are fat, then he is definitely playing you. Men are repulsed by fat women, even fat men are repulsed by fat women.
So all Dr PhD is doing is selling you Hamsterbation that allows you to justify your foolishness. He is not that into you. He is into the other 4 women that he has in rotation probably more than he is into you. Men that like you take the advantage and act on it. Women that like a man do the same thing, they act on it. Any deferral, any excuse is exactly that. If he really was into you, knowing that you are into him, he would jump you. Nothing in the world would stop him from doing it, from wanting to be with you and only you. Men are all about sex. Every fiber, every action, every motivation is to get sex from women they are attracted to. But he isn't, he's playing you.
