Yup. 10 years.
Also 10 years here. Will be 11 years in February that we started dating, following months of flirting online. August 2018 will mark our 11th year living together as partners.
My first partner and I were only living together for a couple of years before he died. Also had some exclusive BFs that went to 2 years, LTRs by some definitions, and I lived with 1 for a year. Problem for me was that I wasn’t exclusive to THEM. I’ve gotta have monogamy or I walk, which I did.
