I think that from my experience at some point you try so hard to get a person back that you get frustrated and then you let go because there's nothing left to lose, you just choose not to let that consume you anymore. I got to a point that it got really draining and exhausting trying so hard and then he showed up anyway when I was fed up with it all. Hope this makes sense

I myself is having a hard time as well letting go. I feel if i let go all is lost and they will be gone forever. Living this way is horrible and your never happy what to do?

I was able to let go coz Self love made me realise that my ex and I wanted different things from our relationship. I am happier now than I was when I was in my relationship.
