Completely agree with all this, seriously Pink isn’t a one-off. My ex would have frankly sulked like fuck in similar circumstances and I’d have ended up at Pink too. It’s why she’s my ex.None of my business mate but seriously could she not go with someone else, one of her family/friends (with you subbing the ticket)? This is potentially a historic night for us blues.
If you go you’ll only be there in body rather than spirit anyway, checking phone every minute etc, and get her wound up for that reason instead…
Worth a try I would say and fair odds she will understand (of course only you know your mrs and how she would react)
