Dilemma is stressing me out

[SimplyTheGuest]

Occasionally my partner brings up a fling I had 30 years ago before he & I started going out together a few months later. He knew the other person involved & won't let me forget it ( we all worked in the same large company).

He brought it up again five days ago & I am so angry! I would have forgotten about it years ago if he didn't keep reminding me!!
I keep telling him IT'S NONE OF HIS BUSINESS, we were NOT even together then!

I haven't spoken to him since (not difficult as we have always had separate houses) & I still don't feel ready to speak to him, but this is where I have a dilemma (and the reason for this post)

In five days time he is due to go into hospital for a knee operation that he's waited three years for. He will be relying on me to get him there & well, just be there for him.

I won't see him stuck but I just feel its going to be strained between us (& I'm not ready to forgive him as its felt like a hangman's noose over my head for 30 years!)
What can I do, I will need to be there for him but my head is all over the place? 🤦‍♀️

YABU - He's going for an operation & doesn't need an atmosphere between you both?

YANBU - He's messed with your head & so can't expect you to just forget it?

Personally I wouldn't be doing anything for this person whatsoever.
He needs to sort himself out and you need to get on with your own life he's not your problem in any shape or form.

What age is he - 5 or even 15 might be acceptable for this BS carry on.

I like this text below. You are not neglecting him just making it clear that this BS has to stop and presuming he is a grown ass man he can take responsibility for his own meds and taxi / drive to the hospital.

"I need time to process that you keep thinking it's acceptable bringing up a relationship that I had 30 years ago with someone when I was not in a relationship with you. With that in mind, I'd recommend that you organise your own taxi service to and from the hospital for your upcoming procedure. I'll be in touch with you when I've had time to process what you've done."

@SimplyTheGuest let him do what he wants as regards to reaching the hospital and getting home! he is supposed to be an adult, albeit a very childish one!!
