I living in Belgium for the past 16yrs,in the begining wasn't easy at all. In Belgium you must know they speak 4 languages, Netherlands,French,German & now English(which is not official).
Anyway I'm living on the west side of the country so more closer to the seaside. It's a lovely area more fresh air.
Inorder to intergrate it's best to learn the language of the area your living in,then its easier to get to know people and the Flemish culture.
