First a little background of myself: 29, have been underemployed since graduated from university, currently living with my parents.

Last night I got another reply from the girl I approached online several days ago in a university forum, in which she gave me her social media id for me to add her. But I haven't been able to muster enough courage to send the application yet. I'm very anxious right now. Because to create an account in the said forum you have to be the student or alumnus of an university. And I sort got the account "illegally". So probably she was convinced that we are in the same university. But actually I graduated from one far less famous than her. I don't know how to answer if she asks some questions like: are you freshman/junior/senior？ or What's your major? So any advice? I'm wondering if I should make a confession at the beginning? or wait until she asks some questions related to it?
