Perhaps it's the other way round

Recently couldnt get the idea out of my mind :s

What if it was me causing people unhappiness

what if it's me?

Can physical contacts be absent in a relationship?

If so, does that mean there is no sparks?

How does one know it is really love, but not any other reason?

There are so many things I dont understand

and not knowing what to do

not knowing, 

is frustrating.
