celan, I'm actually very anti-government myself, hate doing what I'm told and quite honestly think that this is a numbers game and that a lot of this is down to luck and good fortune/good health.
That said, I'm following the rules because it's expected. Everybody is expected to do it and, if it's seen that people aren't doing it then there may be additional restrictions which I don't particularly want as it's difficult enough.
The government has said, 'live together or stay apart'. That's quite clear. I'm no BJ fan but, he's in power and it's a fact that people are dying of this virus. So, this is where it comes back to you. You're advocating - for yourself - that you will continue to see your boyfriend against the rules. What's to stop other people doing that? You say that he hasn't been anywhere... well you wouldn't know if he had or not.
There are lots of people whose mental health is suffering, there was a thread about it the other day, people just inexplicably sad. It's not a special case to be feeling sad and distressed at the moment and maybe for a long while yet.
It's insensitive to post about defying the very clear rules on this and it's winding people up hence the 'FFS' posts. I can understand why they're frustrated. It ought to be obvious to you that posting about doing what you want, in contravention, is going to cause some upset with so many people in a state of alarm at the moment.
I hope your assessment is correct but for many people it won't be a good outcome.
