Love is getting addicted to one person. Anything else is getting addicted to addiction itself, or to sex, which leads to cheating and changing partners and flaky wishy-washy behavior. Falling out of love leaves you in ruins and it takes so much time, distractions, pain and alternative drugs (not necessarily actual drugs, could be food, casual sex, gaming, reading, vegetating). That's why it's difficult to truly fall in love for the second time, even more for the third, etc. Those are my views on love. Probably very unhealthy.
