You mean like neuroscience?
That's a buzz.
You mean like limerance?
You mean like my own experience?
I like the crushing from afar -- the buzz. I know it's just crushies so... it's fun and harmless.
If I want to build serious relationship? I spend around a year there becoming acquainted, bonding as friends, enjoying crushies along the way, see what more is there that could lead to a stronger bond. You kinda CHOOSE to be with someone and commit to them.
So around a year or so if I have chosen to go there, I have pretty much chosen to go there. I'm committed to shared dreams/goals and I find ways to woo/rewoo person to keep getting the buzz.
