“Three top reasons I see:
1.) He’s changed his view or is undecided about you as a potential long-term mate.
2.) He’s a game player who loses interest once he’s ‘got’ you.
3.) He has intimacy fears that are activated at the first sign that he has strong feelings developing for you, so he backs off.
No matter what the reason for his hot/cold behavior, a common outcome can be predicted: if he’s not consistently responsive to you at the beginning of the relationship, chances are he is not going to change and become consistent in the future. As frustrating as it is not knowing why he changed, your time and energy are better spent with someone who is emotionally available to you.”
