Your texts or phone calls go unanswered
For some people, getting a text every two weeks from their crush is enough to keep them hanging on. This is not OK! It’s 2016; everyone knows how a cellphone works. There are no longer excuses for someone not answering you.
If a cellphone breaks, there's Facebook. If Facebook doesn't work, there's email. If email doesn't work, USPS is incredibly efficient. But who goes more than a week with a broken phone? If a person doesn't make the tiniest effort to reply to your text, he or she isn't interested.
You're always the one traveling to see this person
Unfortunately, convenience is king for many people. Your crush might be really into you when you’re right by their house (especially if that means S-E-X). But if they won't shell out $3 for an UberPOOL, jump on a bicycle, or put on roller skates and hold on to the bumper of a truck to come to your neighborhood, the reality is that this person isn't into you.
