If you invite him up to your place, text him for a booty call, or ask him to meet you late at night and you get turned down, this is one of the big red flags when you’re wondering how to tell if a guy doesn’t like you. If a guy likes a girl, he will go to great lengths to meet up once the lights come on to turn them back off and get busy.
If he isn’t answering or is flat out rejecting you by saying things like he has to work early in the morning, he is either with someone else or wishing that he was. What he isn’t wanting is to be with you.
