Perhaps you have more luck than you think. In Malaga there's a big boardgame association that twice a year organize two great events in Mollina, the Zona Ludica and Tierra de Nadie. The first is mainly for board games, and the second is for Roleplaying, but of course you can play a lot of boardgames too.
I Know some people in the area that doesn't have problems with english. And boardgaming is a common languaje ;P
I think you can found a lot of people here to start a gaming group
