What do I do with this girl I really like?

Well you could call her or text her and just say hey hows the vacation? and that could get conversation flowing! Ask how she is and what classes shes taking next term. just try talking to her and you could say somthing like i really wanna go to this (blank) and you could say that it would be awesome if she came (: Hope i helped even a little bit and gotcha thinking! Thanks bye!
