If he/she likes to watch movie, bring him/her to watch movie. After the movie, you two can discuss about the movie.
You can start to ask him/her questions like "how is the day and stuff" and maybe he/she will start to talk about her day.
If he/she is not in the mood to talk, you can tell him/her jokes or stories or stories about your past which might trigger him/her to start talking.
However remember if he/she is too tired to talk for the day and does not want to be bothered by anyone, just leave him/her be. If you FORCE a conversation, it might anger him/her.
Just different types of couples (in a relationship or married) la. I saw some "quiet" couples who didn't talk as much as "normal" la, don't mean they're not loving each other enough ga bor. Don't get a false impression that talking a lot = loving more / more match! As long as you two are happily together is OK la!
its hard to have a lot of things to talk about everyday...but if you do love each other...even just talking abt the weather will be a good conversation
