INTJs believe in constant growth in relationships, and strive for independence for themselves and their mates. They are constantly embarking on "fix-up" projects to improve the overall quality of their lives and relationships. They take their commitments seriously, but are open to redefining their vows, if they see something which may prove to be an improvement over the existing understanding. INTJs are not likely to be "touchy-feely" and overly affirming with their mates or children, and may at times be somewhat insensitive to their emotional needs. However, INTJs are in general extremely capable and intelligent individuals who strive to always be their best, and be moving in a positive direction. If they apply these basic goals to their personal relationships, they likely to enjoy happy and healthy interaction with their families and friends.

"To love means to open ourselves to the negative as well as the positive - to grief, sorrow, and disappointment as well as to joy, fulfillment, and an intensity of consciousness we did not know was possible before." -- Rollo May
INTJs live much of their lives inside their own heads. They constantly scan their environment for new ideas and theories which they can turn into plans and structures. Sometimes, what they see and understand intuitively within themselves is more pure and "perfect" than the reality of a close personal relationship. INTJs may have a problem reconciling their reality with their fantasy.
INTJs are not naturally in tune with their own feelings, or with what other people are feeling. They also have a tendency to believe that they are always right. While their self-confidence and esteem is attractive, their lack of sensitivity to others can be a problem if it causes them to inadvertantly hurt their partner's feelings. If this is a problem for an INTJ, they should remember to sometimes let their mate be the one who is right, and to try to be aware of the emotional effect that your words have upon them. In conflict situations, INTJs need to remember to be supportive to their mate's emotional needs, rather than treating the conflict as if it is an interesting idea to analyze.
Sexually, the INTJ enjoys thinking about intimacy, and about ways to perfect it. In positive relationships, their creativity and intensity shine through in this arena. In more negative relationships, they might enjoy thinking about sex more than actually doing it. They're likely to approach intimacy from a theoretical, creative perspective, rather than as an opportunity to express love and affection. Although, the INTJ who has learned the importance of these kinds of expressions to the health of their relationship is likely to be more verbally affectionate.
INTJs are able to leave relationships when they're over, and get on with their lives. They believe that this is the right thing to do. They may have more difficulty accomplishing the task than they like to exhibit to other people.
INTJs are highly intense, intelligent people who bring a lot of depth and insight into most major areas of their life. In terms of relationships, their greatest potential pitfall is the tendency to think about things rather than doing them, and their difficulty reconciling reality with their inner visions. INTJs are likely to be in positive, healthy relationships, because they're likely to leave relationships which aren't working for them (unless other circumstances prohibit that).
Although two well-developed individuals of any type can enjoy a healthy relationship, the INTJ's natural partner is the ENFP, or the ENTP. INTJ's dominant function of Introverted Intuition is best matched with a partner whose personality is dominated by Extraverted Intuition. How did we arrive at this?
"You are the bows from which your children as living arrows are sent forth...
Let your bending in the archer's hand be for gladness;
For even as He loves the arrow that flies,
so He loves also the bow that is stable." -- Kahlil Gibran
As parents, INTJ's main goal is to raise their children to be intelligent, autonomous and independent. They want their kids to think for themselves and make their own decisions, and so are likely to give them room to grow, and to challenge their decisions and thoughts at key points in their lives.
The INTJ is not naturally likely to be an overly supportive or loving parental figure. Since their own need for expressions of love and affirmation is relatively low, they may have difficulty seeing that need in their children who have Feeling preferences. If they do see this sensitivity, they may not recognize or value the importance of feeding it. In such situations, there will be a distance between the INTJ and the child. This is a problem area for the INTJ, who should consciously remember to be aware of others' emotional needs.
INTJs are usually difficult to get to know well, and difficult to get close to. Those who are close to the INTJ will highly value them for their ideas and knowledge. Although INTJs are generally very serious-minded people, they also have been known to enjoy letting loose and having fun, if others pull them into it. They also can be really good at telling jokes, and exhibiting a sarcastic wit with a poker face.
The INTJ is not likely to choose to spend time with people who they feel don't have anything to offer the INTJ. They especially like to spend time with other Intuitive Thinkers, and also usually enjoy the company of Intuitive Feelers. These personality types love to theorize and speculate about ideas, and so can usually relate well to the INTJ, who loves to analyze ideas.
Many INTJs believe that they are always right. In some INTJs, this belief is quite obvious, while in others it is more subtle. Some people may have a difficult time accepting what they see as a "superior attitude" or "snobbery". Not to imply that INTJs are snobbish, just that some people with strong Feeling preferences may perceive them that way. And some individuals simply have no interest in the theoretical pursuits which the INTJ enjoys.
