self-examination/soul searching...whatsoever

So now half of my ex boy friends who I regarded myself devoting during time have decleared the same complaint
and i bet there should be one more without the necessatation to prove
what's wrong with me?
did i turn myself completely into another person right after the relationship?
i thought i've emphasized that the cut off of contact doesn't mean curelty
but even worse
i was told that i am arrogant when the deceiving mist of romance has been blown away
what have i done to build up the image
just because i am the one who suggested to break?
look
i didn't try to propose an arguement
i just want to find out the causes so as to improve
am i faking a nice guy every time i start loving someone?
god i just dunno what should i do
who to love
how to love
and what is love...
