He Avoids Making Plans With You
Rather than risk your wrath by making plans only to have them fall through time and time again, a guy who’s into someone else will stop making plans altogether. If you suggest things for the two of you to do together, he’ll find everything wrong with your suggestion to make sure it doesn’t happen. That restaurant is overpriced, that movie got terrible reviews, he’s suddenly on a paleo diet and can’t order it, his friend has a thing he has to go to but no plus-ones are allowed – you get the idea.
By avoiding making plans – and, in turn, preventing you from organizing anything – he can phase you out without feeling like he’s hurting or ignoring you. Plus, with a schedule that is free of you, he can spend more time with the person he’s had his eye on since things with you went south!
