You two could find it difficult to talk about your relationship problems in a calm, open way. A good communicative bond will help with this issue, but you'll find that you're both quite sensitive to anything that seems unfair or imbalanced in your connection or your communication. You could both get really worked up when you're trying to discuss a problem, or you could become tongue-tied, not knowing what to say or how to say it without jeopardizing your relationship.
Still, this tricky energy also offers you an important growth opportunity. If you work at it together, you'll be able to build your connection and find ways to discuss difficult subjects. With effort, you'll also be able to learn how to stay calm and open, even when your feelings are hurt. These are important lessons for any relationship, not just a love affair, and if you can put effort into learning them, you'll both come out ahead.
