Don't expect your naturally different ways of viewing the world to mesh together well at all. You challenge each other on your ideas of reality, and you could end up actually hurting each other's self-esteem through the process -- inadvertently, of course! You might have entered the relationship thinking you've got a lot in common, but it becomes clear that that's not the case on a subtle but fundamental level.
Your partner is naturally more practical and grounded than you are. They work hard and they're responsible, and anything less can come across to them as flakiness. You, however, are much more freeform than that. You're in touch with your intuitions on a deep level, and from the outside, it could look to someone else like you're just acting at random when really you're operating based on some deep, inner cues that are telling you what move to make next. This method might actually be threatening to your partner, because they're used to operating based on facts and figures. Calculated risks are their forte, whereas you're good at leading with your gut and finding your way by feel. How to meld the two viewpoints, instead of falling into patterns of challenging and rejecting each other's way of doing things? Instead of trying to control your partner's sense of reality, which is the tendency with this aspect, you both have to try hard to accept your differences. Convincing each other of your own point of view is a frustrating and ultimately futile process.
