So last week me and this girl are snapchatting. I tell her to come over to my house on Friday and she agrees. Friday comes around and we talk a little throughout the day. I get home after school and tell her to come over at 6. She responds 30 minutes later with "I actually don't think I can make it tonight"!" I say "K" and go out and do things. I'm not going to wait around for her. She responds later with "sorry some things came up". I don't respond. Sunday comes around and she snapchats me pics of her looking into the camera trying to be sexy and cute. I wait a day to even view it. Should I try to invite her over again tomorrow or just leave it alone? This same thing happened with another girl a few weeks ago, except what was even weirder is SHE was the one that contacted me to hangout, but flaked on her own plans. This shit happens to me all the fucking time. I'm sick of it. I should also add I'm still in high school.
