How to tell when a guy is no longer interested in you
Look for reduced communication.
This can be one of the first signs that a guy is losing interest. Usually, you can safely assume that a guy will contact you if they want to talk to you.
When a guy that usually calls and texts you frequently stops doing so, you should take note. More isolation and less verbal contact can be a sign of declining interest.
