No need to praise her. 
Perhaps worship is quite pretty.

No need to stay by her side always. 
Perhaps presenting yourself on call is enough.

No need to call every day. 
Perhaps a weekly call saying "hope you're happy" is enough.

No need to message every day. 
Perhaps a rare "love you" reminder is beautiful.

No need of a quick reply.
Perhaps making sure that it's not urgent goes well.

No need of any touch.
Perhaps better to make her feel comfortable with your eyes standing on her smile.

No need of any pricey gifts.
Perhaps a lovely rose is enough. 

No need of any complex poetry. 
Perhaps a compliment is enough. 

No need of regular dinners outdoors.
Perhaps she just hopes you to cook for her.

No need to ask her everything. 
Perhaps observing explains her a lot.
