If you want to show your love to your girl long term, then you've got to have at least a few things that you love to do together. This can be going on long morning hikes, reading together at a coffee shop, checking out your favorite museums on Sundays, going to see your favorite band play live, or really anything that makes you both happy and that you love doing together. While you shouldn't have all of the same interests, you should have at least a few things that you both care about so you can make your love last.

Though it's important to find a comfortable routine of doing a few things that you love together, it's equally important to mix things up and to do new things as often as you can. Maybe you've been playing pool together for years, and it's time to switch to darts. Maybe you've been vacationing in Tahoe every summer; it could be time to try Yosemite.

If you want to love your girl, then you have to love her and yourself as individuals. Make sure you don't lose sight of who you are as a person and she'll love you even more and see that you love her more for it. If you continue to follow your own interests, spend time with your friends, and do some things apart, you'll actually be loving your girl even more because you'll be showing that you're comfortable enough with your relationship that you don't have to spend every second together.  And make sure she maintains her independence, too. If you're both going out into the world and doing your own thing, you'll have more to talk about when you're...

How would you rephrase that briefly using Indonesian?
Pastikan Anda berdua punya minat yang sama. Sama pentingnya dengan mencari rutinitas nyaman untuk melakukan hobi yang Anda berdua sukai, begitu pula dengan memadukan kegiatan dan melakukan aktifitas baru sesering mungkin.
