This girl named Becki likes me to have with her and get married but I'm scared because she's Arab?

She wants me and wants me to use a condom but her dad scares me and I'm worried. I never had before and I don't know what to do, she stalks me and begs for me at me and the other day she said "I love me" I'm really indecisive about it all and should I use a condom if I were to say yes?
