I feel all the things you stated in your first post.I too felt like a bit of a failure and such a let down for having allowed a person into my heart only to find that I was hurt.But I came to understand...relationships take two people...making me only half responsible.I was not in control of the other half.I believe love is a real and obtainable experience.It occurs and it can last forever or be shortlived.It is sad when the love/relationship fades ...if it does fade.But we can try to walk away from all experiences with our focus on the lovely things that occurred...as well as with some life experience from the difficulties.This means absolute crap at the moment for you because you are hurt.Perhaps at some point you can grasp the concept of what I mean.Think back to so many times where you thought...this is it!...I give up!...F it...But you got through and you healed to some extent and things got to be ok again...even lovely.Please know " this too shall pass",and you will be alright again.Don't give up on love.Love can be short lived or last 4 ever...But there is always something lovely within it to carry with you.
