Chris literally has gained all of his knowledge of life and the real world from media. Rich people are always portrayed as cruel snobs who come from "Old Money" that look down on the poor. He has no concept of working hard and building a successful business, earning degrees that allow you to enter a high paying career, or investing the money you've earned wisely in successful stocks. All rich people to Chris were just born into wealth and never hard to work for it.
In Chris's mind if he's emotionally hurt then the other people involved must be emotionally hurt as well. He even went on to say that Colin himself will become emotionally miserable himself. Whether that misery will be due to Colin's guilt over hurting Chris's feel-bads or due to Chris cursing him is unclear, but I get the vibe that Chris is threatening Colin with curses. It's well known that Chris believes that he is able to bring people misery and strife through curses, such as shaking pseudo-voodoo doll LEGO mini-figs and the infamous CURSE-YE-HA-ME-HA. In Chris's mind he an Catherine are supposed to be soul mates and the idea that Colin can make her happy while he and Chris quarrel is unfathomable to Chris.
