No matter how strong your partner is as an individual, they find that this relationship proves very compelling, and you hold a powerful sway over them! Your bond runs deep and strong, and is smooth at times; but at other times, they could feel as if they're struggling with feelings that are bigger than they can handle. Even though they try to maintain their independence, you both might find that feelings such as jealousy, possessiveness and control crop up in you, especially, unexpectedly.
Emotional manipulation might play a role here, regardless of the positive intentions that you both bring to the relationship, and resentments only stack up. The problem lies in the fact that there is a deep and powerful conflict between your partner's need to exist as an individual within the relationship and your need to bond as a unit. Any emotional insecurity that exists in you is brought to light during this relationship, which could be a good thing -- you might undergo an intense transformation and emerge a stronger, more stable person. Truthfully, it's also likely that the road to that transformation is a difficult one. Separations are hard for you; you imagine that the relationship is lost, just because you're not physically in the same space as your lover. The challenge you face as a couple is learning to stand on your own two feet while offering one another genuine, stable support.
