Should boys and girls go to separate schools?

I think boys and girls shouldn't go to separate schools. For me that idea is pointless becouse they won't be able to meet and get to know each other. For instance they won't know how to communicate with different sex person. Probably they would have problems in mature life in particular to find their "another half". Another reason why it's pointless is that introducing this idea will consume much time and money. For all this reasons that idea have more disadvantages than advantages.
