…which drives a person towards absolute bugfuck wild-ups-and-downs insanity? Anyone know? I guess it’s been too long since my last one, and I had forgotten how much of a total nut I become.
I think it’s about wanting something and not getting it. When I’m crushing on someone and it’s driving me crazy, I always think, "I’m a grown-ass woman, and I can get anything I want. I might have to work extra hard for it, or get a loan for it, or do whatever it takes to get it, but I have the ability to get whatever it is that I want. And here this is something that I want but can’t have. 
" So, essentially, it’s a form of temper tantrum.
Limerence is like an addiction to another person. I imagine it’s like getting high and and withdrawal with any other drug, though I don’t have the experience with drugs to back that up.
“It was the best of times; it was the worst of times…”
It doesn’t always end all messed up. Sometimes the crush is reciprocated and two people can spend a wonderful time together, for awhile. Because, by definition, the word “crush” means short-term. (To me.)
If it leads to respect and affection, tho, from like to love, that’s a whole 'nother story.
Eh, species that thought about this too rationally probably didn’t breed much.
