Why are "all" or "some" women like this:?

I've never dated a woman but recently I have but this is what the relationship turned out to become. I've always thought i knew women and what they wanted haha. I met this lady, and we liked each other alot, then the relationship went downhill abecause of religion and beliefs. Then I started to use my lady techniques haha and to keep her wanting me I am doing the following and its working. I'm being mean to her sometimes and calling her names and not calling her and avoiding her all together for a day or 2 and to me she is wanting me more. Why are women like this? I wanted it to be straightforward, like if u like me u like me,. I don't know if I like playing these games to keep her but i will continue if its the only way haha. jw, what u women think about all this. oh ya, im 23 and she is 20 and her dad is strict and she goes to a stric church... just some info
