It is really very frustrating when relationship does not seem to be working, particularly for woman. You should not avoid discussion just because he becomes angry when you ask him about relationship. Do not start talking about your relationship suddenly. Instead you tell him that you want to talk about your relations and fix up the meeting for that purpose only. This will make him mentally prepared for the discussion and compel him to think about it. If he does not turn up for the meeting or show no eagerness to meet for the purpose then probably you are heading for the break up.
