A conversation between two members of society in Anna Karenina:
"But by a marriage of convenience we mean marriage in which both parties
have already sown their wild oats. It's like scarlet fever. One has to go
through it."
"Then we must learn how to inoculate people against love as they are against
smallpox."
I've heard love compared to many things including pie, but never before to deadly diseases. While I agree that love makes life complicated, I'm not sure I'd be in support of irradicating it. It makes life more interesting and at times more fun.
Also, in the book, this discussion began when the were watching a woman who was a little too intimate with a man who wasn't her husband, and the belief was she was in love with him (which apparently she was). I guess back then being in love with someone else would be the only reason a woman would cheat on her husband. Now, since cheating is so prevalent, I think love is more likely to prevent cheating than encourage it.
About another character:
"Karenin was not jealous. Jealousy, in his opinion, was an insult
to one's wife, and one should have confidence in one's wife. "
Well that would explain why I don't act like a jealous bitch-I generally trusts my boyfriends. I'm pretty sure I've said to a bf that was paranoid about me hanging out with other guys, "don't you trust me?"
