I found it so hard to let go when the bastard messed with my head and my heart. The trouble was, although I wanted to, I didn't want to. I just had to stick it out until after all those times of thinking I was over him, then seeing him and everything changing, I finally reached a point where I was relieved. I knew it was 'the time' because this time I wasn't sad about what I had lost, or thought I'd lost, and I wasn't even the slightest bit disappointed at being over him.
Then I started to think about what he'd done to me, and once you get through that initial confusion and hurt - it really does start to get better.
Hang in there!
