It is is sort of about blind adulation, speaking as a bloke here. It's about wanting, needing in every possible way. It's about the constant terror of being replaced, of not being enough. It's about being in love, being in hate, being in a position to hurt without even knowing that you're hurting. It's about responsibility and it's about mutual care.
Note the use of the word mutual. It's the lack of mutual that leads to the hate, the jealosy, the insecurity. It's the lack of knowing that mutuality.
I believe in falling in love. But remember the difference between love and being in love. Love is wonderful. Being in love is wonderful and terrible at the same time. Especially when one loves while the other both loves and is in love. Try to avoid this, if you can.
