Talked to a girl for a while had amazing chemistry and mindblowing sex. We talked about getting serious and shit only to later find out and she admitted to fucking her ex. Of course it "wasnt her fault" he was all over her and other vs excuses for not taking Responsibility. Find out that she wasnt who I thought she was. I'm using it all as a learning experience to further my redpill knowledge and damn have I learned a lot from it but still struggling with oneitis. Any advice on how to deal with a situation like this?
