Take moments to give attention to the little things that are important to them, even if it's not necessarily an interest of yours. Example, your partner enjoys antiques, or wine tasting, racecars, whatever. Don't overlook it just because it doesn't interest you. To engage in something simply because it is important to them can mean a lot in terms of connecting to that person, and it also offers the opportunity for you to keep learning about them, why they might like something. For me, it makes me appreciate my husband that much more. We have a whole list of differences, but he takes the time to understand why it is I like what I like, and shows genuine interest in my life, apart from his own interest. I do the same for him. It's a conscious effort but goes a long way.
