2s feel they need to be needed, and are invested in having people feel indebted to them so that they are important. Unlike 9s, 2s are quick to chide others for being too selfish.
i would agree with this, and i think unhealthy twos can certainly be manipulative, aggressive even, should they move along the path of disintegration towards point 8. i also believe 2 is one of the more common enneagram types infp's in particular are likely to fall into, i have a friend infp who is a 2w1, and also my mom whos an infp, she's either 2w1 or 2w3. but i think it might be best to see a 2 in all its possible levels before ruling it out as a possibility. this is from the enneagram institute website which isn't so bad, i mean its not as comprehensive as DA imo but i generally agree with whats being said here. one thing i did like about that website is you can get detailed descriptions 2000+ word descriptions on each type, so id suggest you check out the ones you might think you're closer to and see what fits best.
Type Two—More Depth by Level
Healthy Levels
Level 1 (At Their Best): Become deeply unselfish, humble, and altruistic: giving unconditional love to self and others. Feel it is a privilege to be in the lives of others.
Level 2: Empathetic, compassionate, feeling for others. Caring and concerned about their needs. Thoughtful, warm-hearted, forgiving and sincere.
Level 3: Encouraging and appreciative, able to see the good in others. Service is important, but takes care of self too: they are nurturing, generous, and giving—a truly loving person.
Average Levels
Level 4: Want to be closer to others, so start "people pleasing," becoming overly friendly, emotionally demonstrative, and full of "good intentions" about everything. Give seductive attention: approval, "strokes," flattery. Love is their supreme value, and they talk about it constantly.
Level 5: Become overly intimate and intrusive: they need to be needed, so they hover, meddle, and control in the name of love. Want others to depend on them: give, but expect a return: send double messages. Enveloping and possessive: the codependent, self-sacrificial person who cannot do enough for others—wearing themselves out for everyone, creating needs for themselves to fulfill.
Level 6: Increasingly self-important and self-satisfied, feel they are indispensable, although they overrate their efforts in others' behalf. Hypochondria, becoming a "martyr" for others. Overbearing, patronizing, presumptuous.
Unhealthy Levels
Level 7: Can be manipulative and self-serving, instilling guilt by telling others how much they owe them and make them suffer. Abuse food and medication to "stuff feelings" and get sympathy. Undermine people, making belittling, disparaging remarks. Extremely self-deceptive about their motives and how aggressive and/or selfish their behavior is.
Level 8: Domineering and coercive: feel entitled to get anything they want from others: the repayment of old debts, money, sexual favors.
Level 9: Able to excuse and rationalize what they do since they feel abused and victimized by others and are bitterly resentful and angry. Somatization of their aggressions result in chronic health problems as they vindicate themselves by "falling apart" and burdening others. Generally corresponds to the Histrionic Personality Disorder and Factitious Disorder.
