Search Results: knows i am heartbroken

So we ended our 2 year relationship over 1 week ago
Im still heartbroken about it
But I blocked him on everything - facebook, instagram, whatsapp, number

So then I wrote this caption on my facebook:
"im selfish, impatient and a little insecure. I make mistakes, I am out of control and at times hard to handle.
But if you can't handle me at my worst, then you sure as hell don't deserve me at my best. THANK YOU, NEXT"

Then my friend (who still has my ex boyfriend on his social media) showed me he wrote this caption few days later:
"Life is too short to be sad and depressed. We must all learn from our mistakes, embrace the new changes and move forward into a positive future.
Everything happens for a reason, its up to us to make the right decisions. Thank you, next"

Does that mean my ex was stalking me on fb?
He knows I like that song
And I wrote that caption "thank u next" first and then I found out he wrote it too
Is that a coincidence?
He hated that song too
Wtf
Does that mean he might not be over me? Or the breakup?
