Hi @Rachb and welcome to the forum. All the above is perfectly normal and common post stroke. The tears and anxiety will calm down over time, this is all a bit of a shock to the system for him, after all, he has just gone through a life threatening experiencing!
Quiet, calm, peace, tranquil, simple, uncluttered, are all words to describe what appeals most to his brain just now. Give him a choice of attending a football match or sitting quietly beside a babbling brook, I know he’ll for the brook…if he had enough energy to get there. So socialising should be kept short and to the minimum until he’s ready for more. He’ll know when he’s ready for more, his brain will make him aware that time when it comes.
The brain will instinctively repels against noise, crowds, busy places and it will be this way for another 6mths or so. The brain is currently healing, doing its mop-up and repairs so it’s currently running a much reduced service 
From the moment you open your eyes in the morning, your brain is taking in information and processing that data. His brain can’t cope with that volume of data just yet, slow and steady wins the race for him just now. He may experience a touch of vertigo in the car, that’s because there is so much information flying in at such a fast rate of speed his brain just doesn’t have processing speed for. I used to just look down at my lap to stop my vision from warping.
He’s only 4mths post stroke, it takes 6mths for the mop-up and repairs, this is the fasted period of recovery. After 6mths recover does slow down but it doesn’t stop. But yes, he will have periods of decompensation, 2 steps forward 1 step back. I always look upon that as the brain’s computer shutting for a reboot after a major update.
A certain amount of his anxiety and tears will also be him mourning the loss of his old self. It takes time to come to terms with and adapt to this new way of life. But hopefully as he recovers more and is confidence rebuilds, and is able to do so much more than he can do right now, that anxiety will shrink back to nothing. Just keep the mood light, keep your outlooks confident and positive.
This can only get better! That’s the way you’ve got to look at it because negativity will only drag the both of down. You don’t need that, he certainly doesn’t need that. Yes, we all had those trips to A&E in the early stages post stroke, thinking we’re having another one. And as we’ve all learnt, they were only the “Braxton Hicks” (false labour pains) of stroke recovery 
Well, anyone who’s had a baby will know them 
The one piece of advice I can give, which should relieve you some, is don’t treat him any differently from the time before his stroke. Let him do everything he possibly can to help himself, that’s the only way to retrain his brain. And give him plenty time before you may need to step in with some help. The more you do for him, the more you slow down the brains re-learning process. If he really needs help with anything, he’ll ask, if he’s mentally fatigued, he’ll defer to you.
And if he manage reading ok then show him these posts, if only to boost his confidence and raise the faith in his future.
I’m 4yrs post stroke, could barely walk, talk, read or write (Aphasia), etc, in the beginning. I do all those now, I can drive, take myself off the gym 5 days a week, shop in busy supermarkets, socialise, have attended parties, barbeques, weddings and funerals etc etc etc. Yes I do still have deficits, such as mild Aphasia, slight weakness down right side, foot drop and fatigue. But none of them things hold me back! It just takes time to settle into new norm, but it will come
In the meantime, just learn to relax and be patient and take some time out for yourself, have a break, have a Kitkat. And remember, inside, he’s still the man you loved enough to marry so take good care of each other
