Well, I didn’t want to spoil the nice thread over there, so I brought this to a new one.
Except for the object of your affection. Like when she suddenly stops calling, stops wanting to see you, stops wanting to talk to you. And, much later, after spending anguished hours trying to find out what you did wrong, you figure out that she was just using you to get revenge on someone for a previous bad relationship. Of course, you were left to come to this conclusion on your own, cause she sure didn’t tell you (honesty, apparently, being above her). You just put things together from what mutual friends said after the fact.
She just went along with everything you said and did (including spending every waking moment with you, holding hands, and telling you she loved you, yadda yadda yadda) to be a spiteful, hateful person.
This can change one’s outlook on life.
But she was good at it. I honestly thought we had something. What a fool I was.
Yes, I’m bitter. The concept of “love” is equivalent to the concept of “bear trap” – something to stay out of, lest it cause you more pain than it’s worth.
