Well that quickly turned...just recovering in the car after my husband had a meltdown over something I disagreed on. 

I'm sorry you have to deal with this, it must be so difficult knowing it can happen so quickly.  When he does get stressed, I guess you are usually the person right there and so are the one in the firing line.

I think walking away is the best option and the best way to avoid inflaming the situation.  I know he struggles a lot with this, but obviously it makes it very difficult for you as well.

He was happy yesterday and smiling yesterday and today he is in a hole.

This kind of reminds me a bit about myself.  I find that if I have a day when I'm actually happy and enjoying myself, at some time, usually towards the end of the day but not always... the thought will hit me that things used to be this way a lot more often and I miss it and once this current little respite is over, it will be back to the new 'normal'.  So I find my emotional lows can come quite quickly after a high.

I do react differently than yiur husband, I tend to just completely withdraw.  I know my partner finds it confusing and probably upsetting.  It happened yesterday and I can tell she's concerned and she does ask what is wrong, but I still feel like I need to keep it to myself... maybe in some guilt ridden attempt to shield her from the worst of it.  I feel bad because at the very least she must find it so confusing that my mood can change so quickly and seemingly out of nowhere.  So I know I need to get better at talking about it with her and reading you post, and all the replies, this morning I think a bit of an apology in there somewhere as well is very well deserved for all she puts up with from me.  I honestly don't know why I find it so hard.

Will this ever get better?

I need to hope so.  I hope your husband can find a better understanding of his own issues and learnt to control them better, or at least manage the effects better.  We all have our own issues we struggle to deal with and for me it makes it a lot harder knowing it is affecting the one person in the world that least deserves it.  Hopefully your husband, like me, sees this and can improve as well... for the both of you.
