INFPs feels tremendous loyalty and commitment to their relationships. With the Feeling preference dominating their personality, harmony and warm feelings are central to the INFP's being. They feel a need to be in a committed, loving relationship. If they are not involved in such a relationship, the INFP will be either actively searching for one, or creating one in their own minds.
INFPs tendency to be idealistic and romantically-minded may cause them to fantasize frequently about a "more perfect" relationship or situation. They may also romanticize their mates into having qualities which they do not actually possess. Most INFPs have a problem with reconciling their highly idealistic and romantic views of life with the reality of their own lives, and so they are constantly somewhat unsettled with themselves and with their close personal relationships. However, the INFP's deeply-felt, sincere love for their mates and their intense dislike of conflict keeps the INFP loyal to their relationships, in spite of their troubles achieving peace of mind.
Unlike other types who tend to hold their mates up on a pedastal, the INFP's tendency to do so does not really turn into a negative thing in the relationship. INFPs hold tightly to their ideals, and work hard at constantly seeing their mates up on that pedastal. The frequent INFP result is a strongly affirming, proud and affectionate attitude towards their mates which stands the test of time.
INFPs are not naturally interested in administrative matters such as bill-paying and house-cleaning, but they can be very good at performing these tasks when they must. They can be really good money managers when they apply themselves.
Sexually, the INFP is likely to be initially slow to open up to their mates. Once their trust has been earned, the INFP will view sexual intimacy as an opportunity for expressing their deep-seated love and affection. More than the actual sexual act, they will value giving and receiving love and sweet words. With their tendency to enjoy serving others, they may value their mates satisfaction above their own.
One real problem area for the INFP is their intensive dislike of conflict and criticism. The INFP is quick to find a personal angle in any critical comment, whether or not anything personal was intended. They will tend to take any sort of criticism as a personal attack on their character, and will usually become irrational and emotional in such situations. This can be a real problem for INFPs who are involved with persons who have Thinking and Judging preferences. "TJ"s relate to others with a objective, decisive attitude that frequently shows an opinion on the topic of conversation. If the opinion is negative, the TJ's attitude may be threatening to the INFP, who will tend to respond emotionally to the negativity and be vaguely but emphatically convinced that the negativity is somehow the INFP's fault.
For INFPs with extremely dominant Feeling preferences who have not developed their Intuitive sides sufficiently to gather good data for their decision making processes, their dislike of conflict and criticism can foretell doom and gloom for intimate relationships. These INFPs will react with extreme emotional distress to conflict situations, and will not know what to do about it. Since they will have no basis for determining what action to take, they will do whatever they can to get rid of the conflict - which frequently means lashing out irrationally at others, or using guilt manipulation to get their mates to give them the positive support that they crave. This kind of behavior does not bode well for healthy, long-term relationships. Individuals who recognize this tendency in themselves should work on their ability to take criticism objectively rather than personally. They should also try to remember that conflict situations are not always their fault, and they're definitely not the end of the world. Conflict is a fact of life, and facing it and addressing it immediately avoids having to deal with it in the future, after it has become a much larger problem.
INFPs are very aware of their own space, and the space of others. They value their personal space, and the freedom to do their own thing. They will cherish the mate who sees the INFP for who they are, and respects their unique style and perspectives. The INFP is not likely to be overly jealous or possessive, and is likely to respect their mate's privacy and independence. In fact, the INFP is likely to not only respect their mate's perspectives and goals, but to support them with loyal firmness.
In general, INFPs are warmly affirming and loving partners who make the health of their relationships central in their lives. Although cautious in the beginning, they become firmly loyal to their committed relationships, which are likely to last a lifetime. They take their relationships very seriously, and will put forth a great deal of effort into making them work.
Although two well-developed individuals of any type can enjoy a healthy relationship, INFP's natural partner is the ENFJ, or the ESFJ. INFP's dominant function of Introverted Feeling is best matched with a partner whose dominant function is Extraverted Feeling. The INFP/ENFJ combination is ideal, because it shares the Intuiting way of perceiving, but the INFP/ESFJ combination is also a good match.
