Should you live together before marrying?

I think its a nice idea to know a person before marrying him/her.. but living together is not the only solution...

Me and my husband both have been raised that is is wrong to live together if your arent married. We dont feel that it is completely true, but we due feel that it makes you lazier about commiting to marriage, because you get that "we already live together" frame of mind, and you say we will one of these days. So we found it best to marry then move in together, but I would say it depends on the people, everyone has the right to their own
