It has been established by previous posts that women have a high probability of destroying you if you play the romance game which means you should opt out of that. However, you still need to keep your place in society and not get ostricised which means it is key that you blend in. One of the ways to do it is ghosting, as in you avoid interaction with them. Which works, but you are putting yourself on the spot by doing this.

I advocate displaying neutrality towards women, treat them like you would treat anybody else. You can have a casual conversation with them if you are put into that position. In this conversatiom you want to ask her questions and display genuine intrest in what she has to say even if it's not important. Keep information about yourself secret and keep triggering her into talking about her self. Casual questions such as what did you do today? And so on. By doing this she won't precieve you as threat and you can successfully blend into society without putting yourself on the spot as a weirdo.
