That is pretty much the same what I asked yesterday or something, I think depending what kind of nerd you are, that you need some other people, men as friends in your life.
Focus on this, this will benefit yourself in the future, instead of only meeting women.
PU is great, women also, but if you want to be happy and have a attractive lifestyle, you need some other people, thats what I think.
If you're working much and have some really interesting hobbies (for women) or something maybe it's fine too, but for me, is that, if you want to have healthy LTR or FB, you need some other people in your life, meaning social circle being good with other people, which nerds are often not so great at.
You can get girls also being a loner or only having other nerd friends, depending what kind of girl she is, but if you're a loner, I made the experience: that good girls without problems won't really stay with you for long, since their love other people and want to do some activities with you. Well many different kind of women out there.
