I wouldn't,, say that immediately. But yes, there is a chance that they were the problem in their old relationship. I am not the one who would like to point out words out of the blue. Though they should think more about the others, i slightly agree with the selfish part as they did just called the NPC spoiled and rotten, not knowing why they act that way. But ofcourse, they must have this past or going through something that it made them feel this way. I will not judge, but they should know what they're saying to others.
(Also i have noticed you also made an alt account to respond to the discussion,, or.. arguement.)
