Especially in SA you can't be too nice in the beginning. Be funny, charming, kind, intelligent. Fuck em silly and that's it.
Let them catch feelings. Don't over text. Let them initiate texts sometimes also. BE CONFIDENT.
Women who are SB's want to be with the confident SD. Let them like you more than you like them. Be the dude who has so many options that if shes not into it who gives a fuck she's easily replaceable. Don't show you are Soooooo annoyed from her being late. Tell her a time and then expect 45mins or so later. Once she is showing more interest. Then you can be a bit sweeter. Women are like pets, like cats in a better analogy they like to come and go as they please. Make them aware you will give them attention and some money but you can go find many more easily. Be the catch. Work out, dress well, etc and make her not want you to stray too far.
Never if it ever comes to this say I love you first. She has to say it. As time goes by the amount you give should be the same or actually less.
