I still feel lost and like I'm not getting over my ex..?

We split back in Oct after nearly 7 years together, we where living out in Spain together and I have now moved back to the UK (stuck living back with my parents), he is still over there living with his new fella that he left me for.

As much as I dislike him for what he done and the way he treated me.. I still think about him every day and miss him, the life's we made together and all we had.

I have started seeing someone else yet as nice as they are all I can seem to think is 'I miss my ex'. I feel so lost and alone. In the 3 years that I have been away from the UK and living in Spain everyone seems to have moved on with their life's and I feel as though I have nothing here anymore, yet as much as I miss Spain now my ex has gone I also have nothing over there..

I thought after 4 months I would feel better but I still don't feel anywhere near over him. I've never felt so lonely in all my life even though I'm surrounded by more people now than ever :S

Suppose this isn't really a question.. just felt like a needed to rant it all out and get other peoples perspective on the situation.
