Women only please?

There is this girl I have known for 2 years, she is pretty religious and she told me that she would date me if we were the same religion. She knows that I like her; she is always writing to me over msn, she is dating this guy from Cyprus. and the other day, she wanted me to go to church with her to see what its like, I agreed to go, but I told her I would not do anything I don’t want to do at church . then we went to lunch afterwards and the guy that she is seeing called her from Cyprus and she was like please don’t say anything while they were talking on the phone, then she said that he is like a friend since he is oversees. If she doesn’t want to date me why is she giving me all this attention, She is the one saying hi whenever she sees me online, I never write to her. she invited me to her b-day party a month ago, on her b-day night I was like text me when you get home, then she wrote back "thanks for being there, I would date you if we were the same religion". When we were having lunch the other day she wanted to know if I would be interested in going to a concert with her, Should I even pursue this? I mean if she wants to hang out with me she must like me right? How should I act around her, or treat her? Does she like me or no?
