From the conversations I've had with my male friends, I can confirm the masculine opinion described here:
"Women are more likely to view cohabitation as a step toward marriage, while men are more likely to see it as a way to test a relationship or postpone commitment."If you are currently living with your boyfriend, or even just open to the idea of moving in together, this post is worth reading - assuming, of course, that you ultimately want to get (and stay) married.
