weird question

i feel weird when i see feel here commenting on someone sad/depressing post about how they don't have that kinda situation (example: like somebody telling about their falling marriage or marriage relating problem and there always comments about how great their husband is and things tat he do for them )....i don't know if you people feel the same....but it kinda make me feel weird...i get this feeling like why people are trying to show off that they are much happier....i don't wanna be mean...its good you have great thing in your life....but its not right to show it off in front of someone who is hurting...that will make them feel even worse (i guess)....i might be wrong and sorry if i offended anybody...didnot mean to...sorry
