I hear you. My husband and I are used to even working together, but right now that isn't an option. He is working nights too, but my managers were extremely sweet and set me up on four days of ten hours so we can have his offset weekend together. Like a few others have said, I never wanted to spend this sort of time with anyone before I met him, used to love just being alone, and I'm still that way except with him. But now, I don't know who jumps up faster when the car wheels hit the gravel, me or our dog.
As opposed as I am to cell phones (or really any phones...why people gots to be calling?), I am so happy he bought us some when he started the graveyard shift. We have it set up so we can send each other emails and the phone will bing when they send. It's just really nice to be able to send each other quick notes through the day. It helps a little bit. A really freaking cuddly cattle dog also helps.
