What was the final nail in the coffin for your relationship? The moment you realised it was beyond saving?
I have just had mine. Mentioned some upcoming dates that I would be working away (15-20th), and 'D'P said we'd need to find a dog sitter as he's booked tickets to a festival with his brother from 12-16th.
It's my birthday on 13th and we've already bought tickets to a gig (his choice). He didn't even realise. Once I pointed it out, he shrugged and said it didn't matter as we could sell the tickets and celebrate my birthday anytime.
