1) Texting on and off. When someone is interested in you, they're interested more than 2-3 days a week, and they let you know when they're busy.
2) You're contacting THEM most of the time. If they're rarely sending the first text or calling you up, they either think they're too cool for that and should go back to high school OR they're just not interested.
3) Always too busy when it comes time to plan a date. Sure some people work 50, even 60+ hours a week, but hey everyone has to eat right! If they can't even meet up with you for a quick bite or just a coffee, then they're clearly the type of person who only "has time" around 11pm at night for a quick lay, or they're just not interested.
4) They say something along the lines of "I don't really know what I'm looking for". This basically equals "I'm not that into you...but I'm still talking to you because maybe I'll be able to get laid" or "I know what I'm looking for and it's just not someone like you but I'm too coward to be straight forward."
5) They talk about their plans but never invite you. If they mention they're going out and they don't even ask you to join (AND they probably always tell you they're busy)...............
6) They talk about other and/or ex relationships. Clearly you're being friendzone'd big time.
7) They're not flirty. This a pretty straight forward hint.
8) You know they're talking to other people. You most likely see it on social media and they're probably not hiding it because they're just not interested in you.
9) You're gut is telling you they're not into it. I know most of us will ignore this but we probably shouldn't.
10) They're not interested in finding out more about you. Convos are short and they never seem to make an effort to get to know you better.
Well, sorry but you really should just stop wasting your time.
