I told this girl I like her and we went on a date around 3 weeks ago but she said she needs time to think because she is against dating within the same fraternity that we are both in. I mean, she kind of broke her rule by going on a date with me, but she needs time to think about whether to continue or not. It seems like ever since I told her that I like her, we've been hanging out more and talking more. It has been 3 weeks ever since I told her. What should I do? Should I ask her about her decision? Advice please!
