i think that besides everything stated also matters who says what and to whom. For instance, as a man i wouldn't take it as a compliment either and would think again a bit more about the woman i have decided to be with. What we don't know though is what else that woman has been saying in general, her past and such. That guy probably has a better idea than all of us and thus he will take everything said her differently from what we read the way she wrote it.
don't get me wrong the same can go both ways, just talking specifically about that case
I agree about looking at it from multiple points as a slight addition of context changes the entire story. Like we don't know if their 2.5 year relationship was doing well at the current state and yadayadaya but I'll just use whatever information available and wouldn't fault anyone for coming to conclusions of their own given with what they have to work with.
It's not a easy subject because if it were, we wouldn't have drama bait to talk about but it's nice to see the comment sections about these things as you kind of get a pulse or new perspective on the trivial subject.
