If there's one thing I've learned about relationships it's that "absence makes the heart grow fonder." Relationships can feel suffocating when one person seems to be latched on to their partner like a dependent child. I know your natural instinct will be to do everything together but don't be afraid to branch off and do things without the other person. Both parties should develop an individual identity and spend time apart working on individual projects or just enjoying quality time with family/friends. Separation is important because it creates longing/desire which are essential in any passionate relationship.
Now being that I'm not currently in a relationship of my own, I might seem unqualified to dish out advice on the matter but I assure you I'm well-informed. From personal experience to that of family members to friends, the stories are all alike and the takeaway is still the same; a little bit of space does a whole lot of good!
