I used to
be friends with a girl I met during my senior year in college.
During that year, we spent some time together and got very
intimate. It happened a couple of times and I would let him have
his way simply because I had developed deep feelings for him.
Eventually, he got tired of me and decided that no communication
will make me disappear. He gave me no warning, no explanations,
nothing. He just stopped contacting me entirely. Every time I'd try
to call him or make plans to meet, he would have an excuse. Even
his friends started acting weird and distant with me. Eventually I
graduated and I wanted so much to see him one last time and say
good bye but he didn't bother at all. We bumped into each other at
the graduation party and made eye contact but he quickly looked
away and pretended not to see me. Unfortunately for me, I boarded
the plane the next morning in tears. Lord knows how many times
I've shed tears from how used I felt and still feel. I've tried
everything and nothing seems to help get my mind of things. I
have no answers since I have never confronted him and, therefore,
am finding it hard to move on. I don't know how to confront him
since I've tried that once before and he simply brushed it off and
said I was over-thinking it. The problem here is that he doesn't
realize what he's done. He doesn't know how much he's hurt me
and seems to think this is not a big deal. All of this has taken a
huge toll on both my self confidence and dignity. It's been six
months since this mess started and one month since I last saw him
(when he avoided me). I am so confused, I do not know whether to
confront him or simple "suck it up" and let it go. Moreover, I don't
know what I want to say to him if I do confront him. I am filled
with pain that I can just burst. Should I simply be honest with him
about how I feel and how much he's hurt me?

Just gba kamu because you have been used and dumped.
The guy knew what he wanted from the outset. He executed his gameplan perfectly.
