When is it time to move in ?

Kalynn

So me and my SO have known each other since we were in grade school and I liked him all through high school and we dated a little in high school. So we just started seeing each other after three years and he asked me to move in with him but we've only been dating for two months and i feel like it's a little to soon. Does how long we've been together matter or does when we feel ready matter more?
