I wonder sometimes..

Do the people who come in-between others' relationships feel some kind of accomplishment for ruining someone elses' relationship/happiness? 
I've always wondered, is that why they choose to keep on doing what they, and everyone else knows it wrong other than stepping back and respecting anothers' relationship?
Shit, I don’t know. I have no respect for you if you have the nerve to pull some grimy shit like that. Just saying~
