Think the worst of them, think of their bad habits, think of them in disgusting situations or doing disgusting things. That will kill any nice thoughts. Think of them as a relative.
You cant kill all emotions....you may try to control them by keeping urself busy with something else
you would look for that feeling when its gone<br />
so taste them, savor them while it's there<br />
for falling in love is the last thing that would make me scared ;)
you cant turn it off like a light switch. time helps. finding someone new helps as well. good luck!
