Relationship advice... 🤔

Me and my partner have been together just over 12 months, we got our first home together after just under 3 months of being together, we love each other more than anything in the world, we idolise each other... But just lately we went through a rough couple of weeks- we acted more like mates than a couple for about 2 weeks.. I work 14hour days about 4-5 days a week so we do struggle in that aspect as I work late and start early! What can I do to get a spark again ? We're back on track but I want to keep it on track..... Any advice will help. Thanks girls.Â
