Does this girl like me?

[Matt]

I like this girl at my school but she could get a lot cuter guy than me. She is probably an 8 and I'm like a 7 or 6 but like in pe we were playing tennis and she was like oh hey Matt... And I didn't even think Megan (her) would even know my name. Also me and my friend messages her on Facebook and my friend was like yeah Matt's spending the night at my house and they were like oh tell him we said hi and I have like barely talked to her and what should I do next I kinda have been flirting with her.
