It is simply more likely the majority is full of immature noseybodies, often with little real life relationship experience, who project an entire lifetime of baggage onto a relationship of two people whose relationship they know nothing about. We all know 1000x more about Drew and Tully's relationship than Tully and Tahlia, yet that has not slowed the Internet love experts down one step when it comes to knowing every single thing about Tully and Tahlia and who is responsible for what and when.
Illogical and poorly thought out ideas do not magically become logical and more well thought out regardless of how many people pursue the same poorly thought out thought processes.
I have been saying since this first became an issue here with Tahlia's tweets that none of us here were or are privy to the details of their relationship so any of us choosing to make bold statements based on non existent information are being foolish.
Since that time, which must be some two months ago, we still know pretty much nothing more about their relationship than we did now, so it is still equally foolish. Tully has chosen to not talk about it at all and Tahlia has given us minuscule tweets that provide no insight at all.
The people who say Tahlia good/Tully Bad are being both ignorant and silly. I myself still have no clue as to what happened, so I don't choose to just fill in the blanks with make believe (perhaps to fill some longstanding relationship hole in my heart).
Instead I flat out say "Relatinships are all super complicated. That Tully was in a lesbian relationship that moved into a guy relationship likely ups the complication factor by a magnitude of ten. Since I don't know much except that Tahlia apparently dumped Tully that is where my judgment begins and ends. Tully is free to move on and Tahlia SHOULD be moving on."
People wantng to expand the tiny morsels of knowledge of Tully and Tahlia's relationship to the point of Tully deserving to be punished or Tahlia being owed something more are just unpacking their own baggage. Based on what little we know neither of those things are actually appropriate and the only normal response to such little information is to wish them both luck in moving on. Nothing else makes sense.
