The hiccups are when she becomes reclusive and retreats. Nothing in our relationship indicates that would be expected and it always throws me off. She never has an explanation for these periods of seclusion, but I always ask for one. Why? I dunno.
Awwww, (((((OldSoul))))). Not to worry. It's not only natural, but absolutely necessary for an Aquarian to "hermitize" themselves occasionally. It's quiet periods of solitude that allow her to regroup, gather her thoughts, revitalize and re-energize. Without those quiet interludes, she'd go nuts on ya and you wouldn't have a relationship. It's not a relationship thing; it's an Aquarian thing. I'm a Capriquarian, so I know and understand our needs. Thank your lucky stars that your wife does this instinctually.
