Over nearly 25 years, we have had our ups and downs, rows and so on. Including a massive row today actually :( But, we have stuck together through very difficult times. We have supported each other, but I think the balance lies with him:
When I nearly died in hospital many years ago, he sat holding my hand every day and could hardly be parted from me for a minute. He kept it from me that I was definitely going to die in three hours or so.... and I didn't!
He kept going when suffering from deep depression and somehow managed to look after the DCs even when in the depths of misery and I was working full-time.
Even though he has multiple severe health issues and disabilities, he still manages to keep the household going - shopping, cooking, finances etc.
He looks after me with my own severe health issues, sorting out my meds and doing everything to ensure that I can rest every evening when I get back from work.
Despite my nasty temper, he puts up with me when I am spoiling for a fight, like today!
