A terrible thing has happened

[TheLittleMonster]

Today, whilst on Google chat to OH (long-distance relationship), he said 'should of'. When I tactfully questioned this, he said that it was not an error, but a choice made to save time! He refused to back down. What to do? Can our relationship survive this?

No.
I'm sorry. You asked.
It's the slippery slope from here.
Next thing you know he'll be putting 'orange's' on the shopping list and maybe even saying 'I were'.

I wish I could be more optimistic about this, but I feel like I'm saving you from future pain.

I suspected as much. Do you think counselling would help? Lessons?

You could try. You could try.

But think of your future children. What if one day he refers to them as you're future children? Could you live with yourself.
Well could you?

Well, at least he knows it was wrong...

You could tactfully point out that "should've" would have been the same number of keystrokes and less likely to make you stabby.

Relationships are about compromise. Rather than insist on "should have", could you meet in the middle with "should've"?

Grammatically correct but also time-saving.

Cross-posted!

You're right. Compromise is the way forward here. Maybe I should give him another chance. Just the one, mind.
