Such a Mom Thing

So, my mom's best friend (Deb) has a son (Tanner) who is my age, and both moms have been trying to hook us up for about a year now. I've met him a few times and he's pretty cute, but I can feel that he does not like me. My mom told me he's gonna be in town on the weekend of May 16, but I have to go to Lupe's Sorority Formal that weekend. I told her this and she said, well maybe he could come down here and go with me to it! Then she said "I emailed Deb and told her that you couldn't come up and why and that Tanner can join you at the formal if he prefers..." Why do mom's do this? Now it looks like I asked him through our moms! Ugh! It's already awkward between us, because we both know that our moms want us to hook up, but now it'll be even more awkward since my mom invited him to some prom with me!
