Or "living in sin" as @The Reverend would call it, with your S/O without being married. Answer these questions for me: Are you currently cohabitating? If not currently, have you ever cohabitated? If you've done it more than once, how many different S/O's have you cohabitated with? Do you think in 2018 cohabitation still carries stigma?
I don't currently live with my partner (seeing as we've been dating less than a month) and have never lived with a partner before. I don't think it carries any stigma with the vast majority of people anymore and is an important step to take to see how you handle it before commiting 100% of the way/actually getting married.
Some people cohabitate all their lives and never get married I think there is still stigma about that
Yeah, the definition is an unmarried couple sharing a living space How many times have you cohabitated before you current situation?
Dating your roommate isn't exactly the same thing. You had different bedrooms but shared common areas like kitchen/bathroom right? Cohabitation is usually when a couple shares a bed/bedroom
