why keep posting about it every few weeks pretending to want to hear what others do/ would do?
Odd, isn't it. She posts the same thing every time and gets told the same every time. The only thing that changes is "I'm can't move on from a man who left me 5yrs ago... 6yrs ago.... 7...."
And yet in all this time, despite his obvious love for OP, he's never got back with her, but managed to date several other women, has moved further away, blocks OP and won't have his children nor pay for them. Around once a quarter, he throws a few crumbs and OP dances around at the words of the man who loves her. He knows that's sufficient to keep her quiet for another few months.
We've all tried spelling it out. We get told we're clearly jealous/can't stand the idea that he obviously loves her. As if all these strangers online, who have clearly taken the time to try and show her what a mockery he's making of her, and how she's wasting the one life she has, are actually all wrong and have some kind of ulterior motive.
But yes, the continued pretending to want to hear others advice, just to argue how it's all impossible unless the answer is "shag your ex" is weird.
