You were his first love. It's understandable that he's a little torn up after the breakup. You don't love that he's still contacting you, but hey, you're a nice person. You try to be understanding of what he's going through.
Oh, I should also mention, you thought your ex-boyfriend was far away in another country where he couldn't randomly show up and stalk you. You were wrong.
You woke up nice and early this morning and went for a jog. Stretching it out outside your apartment building, you were all like, "This is gonna be a great day."
All is right in the world.
Out of nowhere, YOUR EX APPEARS.
And you're pretty sure your face is like:
HOLY CRAP. WHAT ON EARTH IS GOING ON RIGHT NOW.
You wish so, so badly that before he hopped on a plane and flew 3,000 miles to wait for you outside your house, someone had been there to tell him…
That's the worst idea ever!!
What were you thinking, dude?! You honestly think I'm going to be okay with you turning up outside my building like some crazy stalker??
Nobody likes when a significant part of their past turns up unannounced on their doorstep. Nobody. Especially when that person lives in France. SO YOU MISTAKENLY THOUGHT YOU WERE SAFE FROM THIS KIND OF NONSENSE.
You guys have an awkward conversation. It mostly centers on what they're doing in New York, your surprise at seeing them outside your house at 7am without any warning (hint hint), and when they can see you again (because it's clearly time for a conversation about boundaries).
But the super-freaked-out, kinda scared person inside of you is just like:
It's time to move on.
I get that this is hard for you, but it's over. And that means your emotional healing is your responsibility. I shouldn't be the one you're coming to for answers. You need to find those on your own.
Preferably back in France, and nowhere near my place of residence.
You go inside, and look out your window to make sure they're gone. You hope to god this is the only time this ever happens (oh my god please don't let this become a pattern).
You go to work, looking over your shoulder every now and then, and prepare to have a pretty weird day.
But actually. THIS WAS MY MORNING, FOR REAL YOU GUYS.
