Myself and my Girlfriend were in exactly the same situation 5 years ago - we moved to Spain and have been here ever since.
In my opinion to make a go of things successfully inSpain you need at least 1 of the following things : Sufficient savings to live on for a minimum of 12 Months ( Assume that either of you will not be able to get a job before that time ) ; A profession or qualification that can easily be transferable or useable in Spain ( Like an Electrician, Dentist etc.. ) ; Good Language Skills ( Spanish would be good , if you can speak German or French aswell that would be even better ) ; a Support Network ( Will you have freinds or family living close by ? )
