It's painful and awkward when a man rejects you. It's worse to ignore or rationalise his behaviour, wasting time and self-esteem. Avoid rejection by noticing these cues.
he's doing you a favour by being there, he doesn't care. You make plans, but he's more flexible. You might never hear from him if you stop trying.
His thoughtful texts and conversations have been reduced to monosyllabic responses, and phone conversations have been cut short.
Men naturally compete. Jealousy is natural, but you don't want a possessive man. If you talk about other men, mention your ex, or another man flirts with you, he's lost interest.
Conversations are centred on him. He doesn't inquire about your personal life. When you do speak, he shows no interest or listens at all.
He doesn't share much personal information, doesn't open up, and you haven't been able to emotionally connect with him.
