He said something today that scared me. All day i felt unsettled in my stomach. I went to him earlier when it dawned on me as to why this attack on another person disturbed me--i dont know him to be an agressive person. My whole life he's never had a malicious side. He scared me because i dont really know him. His outburst (aimed completely at someone else) alarmed me. It exposed a hole in our intimacy--and revealed a limit we had not been aware of. If he was capable of rejecting this person based on a careless overlook of taste and conversational tact, was he capable of rejecting me?
