I asked him to move out - and other boundaries (he's untreated, ex-fiance)
Background: we're both 55, no kids, known each other since high school (platonic back then); been together 4+ years, ages 50-55. He asked me to marry him in 2010, though he still flirted seriously with other women. (Disrepsectful to me. This kept up, but at a decreasing rate, for two years. He finally quit that in 2012, when I enforced my boundaries in a LOT of areas.)
