Love / She's muslim and I am christian, will it ever work? Has anyone had similar experiences [63]

I would like to give you an sensitive advice:

Get off this relationship. Or love. Or whatever it is at this stage. This hard facts will not change and you can feel immediately if its worth it fighting for or not. After some weeks of crying both of you will find a match..

Its not about religion its about attidute and willingness.

Real Estate / Buying a house and staying away from the border [3]

All in all you will have to contact the local authorities.
You want to buy an existing house. Thats fine for everyone- EU citizens the same like locals. This house has already some land - that is outlined on local plans, the bordes of the ground stay like this. If more land is needed you contact the local authority.. they will tell you about the designations in that special case. E.g. if there is an obligation to build/ restriction. You can only buy as is written in the cadastre of muncipality. Too close to somewhere isnt possible - the owner counts.
