Lol this is actually fair, thanks.

However, I would say though that OP says either way it means the relationship prob should end. If it's an observed view, you really can't make that call unless u know the intricacies of the relationship in question. I've been in a relationship like this that went to shit, and a relationship that was like this for a period and then we got through it and was basically fine. Seen plenty of other friends make it as well, ofcourse to varying degrees, but it's not an uncommon speed bump for a long-term relationship.

Edit: Just re-read my reply and think my argument is flawed lol. Originally I thought OP speaking from experience (while claim is that relationship should end) then argued that if speaking from observation, then wrong to think relationship should end (cause they don't understand relationship). These don't line up haha. I think regardless of if OP got burnt or if observation, every relationship is so insanely different that you just can't blanket say u should end it. Ok I sleep now.
