🎧Leo and Rebecca Buzz Question - So, here me out. My new girlfriend rocks and we are moving along very well in our relationship. But, now that we are official, she has asked me to GET A NEW PHONE NUMBER! I've had this number for a grip and really don't know why she would want me to get a new one now that I'm with her. ????
