My inner lesbian is sad

A really georgious girl followed me on Instagram last night and at first I didnt know who she was. I started texting my bestie and he was hyping me up to finally text her until I recognized her. She was my mom's friend's daughter who had spent the summer at my house over summer vacation for family reasons. She has a boyfriend and is straight as a ruler, which made me really sad. I feel like every girl I try to get to know or try to flirt with ends up being straight, it's like all the lesbians went into hiding! I know I'm just a freshman and I have plenty of time to date and blah but I have been really lonley for the last few months and I really want to find a nice, sweet girl, but they apparently dont exist when I'm around. It's just aggravating, you know?
