One-year anniversaries are cool and everything but there are a lot of significant relationship milestones that go unnoticed, like when you start leaving stuff at his house. That's the day you stop pretending everything you need for an overnight stay actually fits in your tiny clutch. LOL, if only. That's the day you unleash the real you on his medicine cabinet, tampons and all. It's a momentous occasion, OK.
Unlike an anniversary though, this milestone has less to do with how long you've been dating. According to Laurel House, dating coach and resident sex expert for My First Blush, "Every relationship progresses at its own speed and time generally has little to do with it. Some daters see each other once per week with infrequent talking or texting in between, and this can carry on for weeks, months, and even years. Others see each other several times per week and are in regular contact almost immediately."
There's no right or wrong way to do this, just whatever works for you and your partner. Consequently, House says, "When you should start leaving things at your partner's place has everything to do with your comfort level and your combined dating purpose." There are three ways you can tell if you and your partner are on the same page.
