Do you think this is why my boyfriend is Non-chalant?

he would see any display of emotion as a weakness, a weakness that could be taken advantage of, that could hurt him, time may lessen this as his security is improved, but his reactions are understandable. Are you willing to be patient, and undderstanding, in the hope he may one day change, why fall for someone you want to change, i see this may be difficult to live with, but you fell in love with him just the same,
