What happened to love?

So, I was dating this girl, and I told her that I liked her, but she told me she had just broken up with her bf and that she wasnt ready for a relationship, but we continued to hang out. I, of course, still wanted to be her bf, and I felt like every time I went out with her I was falling for her more and more. But she played a lot of games with me she would tease me, talk to my friends and say some things, but tell me different things in my face. The games got me annoyed, and they went on for months, and throughout the months I knew I was falling in love with her. But the games got out of control they had me so annoyed that one night I couldnt help but cry, lol I know its a little feminine, but w/e I have anonymity here. So, after that night I told myself, "screw it women arent worth all this heartache", so I moved on. But then just a week ped and then she was all over me. And now we're bf/gf. But now that we are together I dont feel the same love for her anymore. What happened?
