How to tell when a guy is no longer interested in you

Choices: a. However, don't think of it as a temporary effort to win him back. The guy might have only met you once, so he might start talking about no longer wanting to have sex.; b.

This doesn't necessarily mean he's not interested, but it may mean he doesn't want you to talk to him anymore. Underestimating your ability to communicate is one of the physical signs of a difficult relationship.; d. Pay close attention to how early or late boys display a decrease in their communication. You could take this as a sign that they don't want to be friends anymore.;
The answer is:
b.
