My BF deals with difficult feelings really quite badly - he withdraws and goes very quiet when he's upset, to the point where he will 'freeze': he folds his arms in tight and closes his eyes to shut out the world.
It feels like being given the silent treatment by someone in a huff, but it isn't that; he genuinely doesn't seem to be able to help it and he only does it when he's really upset.
I find it really hard to deal with when he's like this (it doesn't happen often) and I can get very upset about being shut out - it really feels like rejection to me.
However, I've had a good think and realised that although I don't like his way of dealing with emotions, I can't go on making it all about me and getting upset - it means that I'm not being supportive when there are real things that he's upset about and that he gets completely overloaded by the double whammy of the thing he was upset about in the first place and my being upset about the way he deals with it. It makes him feel as if he can't do anything right and is useless.
