I think that's why Derek is so bitter; he was forced to be on his own for so long because Kate killed his family and this happened when he was a teenager, so would forever cloud his relationships in the future (she was only with him to find information on his family).

He's afraid to let anyone close to him because he thinks they'll leave or betray him; so far, he's not exactly wrong on this - his pack is leaving and Scott has (or appears to have based on last week) betrayed him.
