This is your friend with benefits. Who you totally want to be your boyfriend. Who treats you like his girlfriend… Until someone he actually wants to date comes along. Then he puts you back on the shelf. Then, when they break up, he texts you to see what’s up and the cycle starts all over, until he puts you back on the shelf again. And all the while, he never deletes Tinder from his phone! LESSON: Do you really want to be someone’s place holder? Life isn’t a Hollywood rom com; he doesn’t realize he’s in love with you in Act III — this is a never-ending miniseries of him treating you like a security blanket.
I'm not going to fuck him anymore, now I know he's just a shelfer.
