Bebop has some good hints. My husband and I do a lot of hugging and have little "rituals" that let each of us know we're thinking about the other. When I stand on a single step, I'm just the right height to fit into my husband's arms nice so we both look for single steps, LOL. At night, I insist my husband pat me on the bottom like a little kid before I go to bed (I usually go to bed before he does) but it's just a fun pat, makes me feel cared for. He does a lot of telling me how much he appreciates me, thanks me for chores I do for us/dinner I make, etc. and I'm constantly looking for little ways to please him, surprises and things I think he'll like. We have our own jokes and things we see and discuss together, shared memories.
