You will cry.
You will be angry.
You will be in grief.
You will even be tempted to contact her again.
For me, I felt all the above, and more. For 6 months, I was living
in emptiness, thinking mostly of her. Things like, how many things
we could have done, how we could still do many things, and how we
could get back together, etc. But things were just not meant to
be.
A few days ago, I lost control, and sent an sms her, telling her
how much I missed her. She never replied, and the next day morning
I saw her, she was just, well, herself. That reply never came. Of
course, I never expected any reply from her. But deep down, I still
hoped that she still felt something for me. However, circumstances
showed me the answer.
That moment onwards, the final tie I felt that held me to her was
finally severed. Initially, I felt empty, numb. I felt that I had
finally hit rock bottom. And since there was no more way to go
down, I went back up. By the end of the day, I felt as though
something had been taken away from me. I felt relieved. I had never
felt so relaxed for more than half a year. It was like all the
grief and sorrow had been removed finally. I felt new. Refreshed. I
could finally start anew.
These few days, there has been no relapse. So I believe the
negative feelings are gone for good. And I will no longer want to
get back together with her again.
So my point being, you will ask. My point is this. You need to do
something/s that will make you severe the ties holding you to her.
She most probably doesn't give a damn how you feel. Most probably
she has no ties holding her to you. You can cry, you can be sad.
But to stop the negative feelings from controlling your life, seek
some ways to cut them off.
For me, that final cut was the last sms, and her no reply. For you,
I dunno. You will know. And after you have done it, you will be
released, just like me, and be able to start afresh.
I wish you well, and hope that you recover soon.
