Hi Petal~flower.
Certainly seems like he dumped you so he wouldn't feel guilty about sleeping around and acting like a 'lad' living his own life by moving so far away. Now he realises it isn't all that great and thinks he can just get back with you.
Listen to Beautiful South's "A little time" sounds just like him!

Are you sure the only reason he doesn't want to move back is because he needs to come back to the area and it's convienient to just take back up with you?
If this was me I wouldn't go back to him if he had hurt me so bad but it's easy for me to say that being on the outside, you must be feeling some turmoil but remember it is him and his behaviour that is causing that, do you really want him back when he can make you feel this way?
I wish you all the best Petal :o)
