I (29F) have been engaged to my fiancé (32M) for 8 months. We’ve been together for 3 years.
My ex (33M) and I broke up 4 years ago. It was a clean breakup. No contact. No drama.
Or so I thought.
About two weeks ago, I started noticing someone outside my office building after work.
Same time every day. Same place.
At first I ignored it.
Then I recognized him.
My ex.
Standing there like nothing had changed.
I avoided him the first time.
The second time, he stepped forward and said:
“You’re still ignoring me.”
I told him he had the wrong person.
He smiled and said:
“You always said that when you didn’t want to deal with things.”
That made me uncomfortable, but I walked away.
I didn’t tell my fiancé right away because I didn’t want unnecessary stress.
But then things escalated.
My ex started showing up in places that didn’t make sense.
Near my gym. Near my apartment complex. Even once near my fiancé’s workplace.
Always calm. Never aggressive.
Just… present.
Like he was waiting for something.
Then one evening, he approached me again and said:
“You didn’t tell him everything, did you?”
I asked what he meant.
He said:
“About us.”
I laughed because I thought it was manipulation.
But then he said something that made my stomach drop:
“He thinks I disappeared. Not that you ended it.”
I told him to leave me alone.
That’s when he showed me something I wasn’t prepared for.
A printed photo.
Of me and him.
Taken from a time I don’t clearly remember—sitting at a café I’ve never consciously been to.
He said:
“We didn’t end the way you think we did.”
I left immediately and told my fiancé that night.
I expected concern.
Instead, he went quiet for a long time.

Then asked:
“Why would he think we’re still in contact?”
I told him everything.
But when I showed him a photo my ex sent me later (same café picture), my fiancé said something strange:
“I’ve seen this before.”
I asked where.
He said:
“In your phone. Last year. You showed me this exact picture and said it was an old memory you wanted to forget.”
I checked my gallery.
Nothing.
No photo.
No trace.
So now I’m stuck between two versions of reality:
My ex insists we never fully ended.
My fiancé insists I already dealt with this before.
And I can’t find any record of that conversation happening at all.
Yesterday, my ex left a note at my door.
It said:
“You’re only telling him half of what you remember.”
So I told my fiancé everything again.
And this time, he said:
“Or maybe you’re only remembering half of what you chose.”
So AITA for bringing my ex back into our lives by reporting this…
or am I the only one who doesn’t fully understand how the breakup actually happened?
