I know most ppl have problems with being a white knight when they first come to this sub my problem is the reverse.

I've never been an emotional person and emotional displays tend to annoy me. My last 3 relationships ended under the lines of me being to cold. When and how should I show emotional support? I've been told that I am 'unsympathetic to the point of being cruel' in my situation what would you change to make a 'frame'? I have no problem starting a relationship but I can't seem to maintain it more then a month or so.
