questions??

okay I'm just a small town girl who grew up in Albuquerque New Mexico I'm in middle school now I'm in 7th grade and I have a crush on this 8th grader name aldofol me and him are like sort of friends but we're not so it was my birthday one day and he texted me "happy birthday baby girl I hope you have a wonderful day" so I was thinking to myself when he texted me that on Snapchat why would he send me this and also thinking he has a girlfriend so why would he call me Babygirl?
