You two have some basic and important differences when it comes to how life should be lived, and these differences took center stage as soon as you tried to build an intimate relationship. Your senses of individuality and your needs for intimacy are directly in conflict, in part because you're both out of touch with your need for space within the relationship. The bond between the two of you could become a confusing push and pull between togetherness and individuality, the classic pursuer - distancer relationship.
There is a strong bond between you, but you're trying to preserve that bond while your lover fights it, viewing it as a threat to their individuality. This push-pull could come in the form of frequent arguments over all the things in life that are most important to you -- your values in a relationship, your politics about gender roles as related to love affairs, your hopes for the future in terms of marriage, kids and whatever else you might really want -- or really want to avoid. You have a hard time laughing about your disagreements; you both feel too wounded and threatened by your differences to be able to accept them calmly. And through arguing your own point of view, each of you is subtly trying to dominate the other -- and that leads to some major clashes. This is a very unstable and difficult aspect to deal with in a relationship, and it takes plenty of patience on both your parts to get through it.
