I think just talking about each others days, and making it a priority to do things together outside the house is probably a good place to start. Things you both enjoy, My husband told me once that I was his best friend. I was surprised, by his answer since he thinks so hightly of a couple of his friends. But I think it is because we make each other a priority before our friends. My husband is insistant about me trying things I might not otherwise try, because I am such a homebody. Once I do he asks, now aren't you glad you tried it. Sometimes my answer is yes but I won't do it again. and he is okay with that at least I tried it once. So i think trying to experience new things together is a way to increase the bond we have. hope this helps.
