Yes it does feel like being home. It feels like you're with your best friend, who you also want to fuck. It feels spiritual, like you knew them in other lifetimes. It feels like unshakeable confidence, I *know* that this is my soulmate and whenever I think of growing old with him, it feels so right.
We've been together for almost 6 years and known each other for 10 years. The anxiety of the honeymoon period is gone, but the passion is still there.
