We often expect everyone to pamper us, and give us the best emotional treatment. When that does not happen we feel hurt. Then we retaliate. We may hurt the person back. Either through silence, or some comment, or some action. We often forget the shoes he is standing in. He could be undergoing a major stress or problem which he may not be able to handle. That person still loves you, but was unable to express it at that moment due to his stress. Accept his cold attitude. Don't feel hurt.
Be kind, everyone is fighting a battle.
