Thank you Enigma. His break up was not as messy and drawn out as mine, in fact it was an amicable break up. He is therefore a bit further along the 'moving on' process than perhaps I am. But, I am determined not to let the damage my ex caused stop me being happy with someone else. I am a LOT more wary now though, and am trying not get too attached or jumping straight into anything too intense. But for now, we are spending time together and having fun and I am SO much happier than I thought I would be :)
I know there will come a time when the ex won't pop into my head but, at the moment I am not quite there yet.
