I feel like marriage is being weakened by the internet, honestly. People seem to have this ideal in their minds of what love is supposed to look like, and if their current partner isn't cutting it, they just get online and look for the next. No one works for anything anymore, and I think people give up on things way too easily these days. Every successful married couple I know says that it's work to keep a marriage together. Not that it's ALL work and never enjoyable (obviously), but that once limerence fades away (roughly 1.5-3 years), what's left is making a choice everyday to find new ways to fall in love. I feel that nowadays as soon as people stop feeling the "spark", they go out and chase it elsewhere. It's sad, really.
