Op went back to his country, and judging by no movement of that address, he probably arrived at the scene of someone jumping on the ex, and they probably fought and he probably died and took the password with him to the afterlife, well lets hope that he can spend the coins for some virgins in heaven, if they accept bitcoins there though.🤣  lol.

Good find! Hehe and besides who will sold his laptop on a flea market while he is holding huge amount of Bitcoin that time. He doesn’t need to sold anything if you have more than a million dollar on your crypto asset. And I doubt someone holding the .dat file of the wallet address will give it to him by just knowing he knew the password. It will just makes thing hard for the OP to get it because the value it contains is worth a fortune if someone manage to brute force the password.

In that case, you should do whatever it takes to win back your ex girl friend, if you really know what the 19,400 btc can do in your life (or both of your lives) you should work hard to get her to forgive you. if she still has the p/keys this is the easiest way to solve your problem, travel to her wherever she is and reconcile, am sure if she knew you are now a millionaire she will forgive you in a heartbeat
Although I still find it odd you gave your ex gf the backup of the seed phrase and you don't have it yourself. Why would you do something like that? obviously you knew the p/keys was important that's why you made a backup but as clever as you are, you fail to have it yourself.

I can't understand the concept.
it was 2 PM and you remember exactly an alpha numeric code of something that you really didn't give a damn about (since you lost it without even backing up your private key?)
do you remember the address but not to make a back up? or to don't sell your laptop? ( maybe selling a portion of those bitcoins prevented you from this laptop sale...) mmm 

@wilsder
I do not enter the veracity of the story ...
but I ask myself, after all this time, without having any kind of back up, how do you remember exactly this address?

you have completely forgotten that you have bitcoins or make any back up and do you remember the address?

Then may be you should tell the person to come and speak on your behalf if he/she is still active in the forum, as it is, nobody believe your story. Even i find it hard to believe that someone will forget about an asset worth over a million dollar. i don't know what kind of hardship you went through but i believe when someone is going through financial hardship that's when their brain becomes aware of what they own. Or you suffer a memory loss withing that period that prevent you from remembering. Whatever was the situation i wish you success in your quest if actually you are truthful.   

You went through a difficult period in your life but so some reason forgot that you have over $6M worth inside your laptop,  and just sold it for just maybe around 1,000 dollars to save you out of the bad situation you were in (the motive behind selling a laptop in a flea market is obviously money)... really?

How messed up you must have been?
