This is what I would do:    Tell her you are attracted to her and would like to try us for a while to see if it works. If not then I am fine hanging out every once in a while as friends but I would make it clear to her that you will be dating other people until the right one comes around. Tell her you don't want to do that but you can't wait around just to see if the other person might want to give it a chance. You have to show her that your the man and it's going to be your way if she has any interest in you. You don't want to start a relationship with her controlling it anyway or she will run the relationship forever. You won't be happy in that situation so show her your a man.    BTW, not all devote hardcore Catholics are good girls. I went to a Catholic school part of my life and the girls there are bottle up and ready to explode.
