One of my male friends whom I don't get the chance to see very often (but everyone thinks he is interested in me) confuses me with his texting habits. If I text him he texts back almost immediately. However, if I say something like "I'll swing by sometime" (he works in a place of retail) he doesn't respond at all. Yet, if I see him out somewhere he acts as if he is overjoyed to see me. Or if I text about something else he again responds almost immediately. I will say he is the epitome of that whole nice guys finish last saying. He has been hurt more than once before and tends to put up a front of acting like a POS when he isn't at all once you get to know him. So i never know if he isn't responding b/c he doesn't want me dropping in or if he just doesn't want to put himself out there. He also sometimes responds, again almost immediately, with only an emoji. Any advice here guys?
