With Fluffy on this for sure. The rest are definitely pleasantries and lust, if anything. In my experience there are varying levels of love (you can love someone, but not be in love with them, as I have found out).
Most of this shit you only learn with time, and of course, retrospect. I can say that now after coming out of a near 5 year stint with my partner. Splitting with someone after 5 is pretty crushing, so I feel for those who've done 10, 15, divorced, got kids/home etc. What a mess that must be.
So it's back to ploughing through duds again for me til I find my a diamond, or precious metal of sorts.
