Sometimes, life gets busy, people get tired or focus away from their SO (on projects or other hobbies).

What do you do to bring the sparkles back, focus on your SO as a priority or simply bring back a bit of the honeymoon phase?

I feel my relationship is becoming a routine. I'm short on ideas of things to do to make it more active and unexpected.

SO hasn't complained but I'd like to surprise him :p

Any ideas?
