People don't think straight when they think they are in love. [1] In my family we've learned not to confront people directly when they are experiencing this (even when it was me) because it's a delusional state where people won't listen to you.

Co-incidentally, I recently read the book referenced in the article:

While it's short on prescriptions for actually overcoming limerence, I found it helpful in at least understanding the mechanisms driving my limerent feelings. If you want help coping with limerence, the tribes.com forum may be of some help (though a fair amount of it is simply people broadcasting their neuroses). I have found some nuggets of good advice however:

It's hard to say whether limerence is in and of itself a problem. Tennov takes a NPOV. Certainly, if you're supposed to be working and instead you're daydreaming about someone it's a problem. Like a lot of things, it lies on a spectrum from pleasurable to pathological or dangerous. Still, I would agree with the author's point that understanding the distinction between limerance and love can be helpful.
