You don't have good north node aspects.
I wouldn't quite put it that way. You don't have very many aspects to your nodes, period. Lack of aspects to the nodes, in my understanding, often means there isn't much to your karmic past story. You're coming out of a past life, or lives, where you lived, you died, and while your life would have included superficial changes, nothing much changed for you or challenged you on a deep karmic level.
However, I looked at your chart for a while, at what little karmic information it does give--sign and house placements of the nodes and their rulers, and what few aspects there are--and I see a clear story emerging, which would explain your need for independence, and probably your attitude toward relationships as well. Not only is that indicated in your birth chart for this life, it's also a reasonable response to the past life story I see here. (Feel free to believe, or not believe, that this is your actual past life story. The real details may be different, and if you don't believe in reincarnation, it's fine to take it as just a story.)
The only aspect you have to your south node is an opposition to the sun, in Aries in the fourth house. The other place to look for karmic past clues is the south node's ruler--in your case, that almost completely unaspected Venus. So not many aspects to tell the story, but sign and house placements say a lot.
South node in the tenth house suggests a life in which you had a high social position, a reputation to maintain, a strong career. In some way, you were highly visible in your society. Libra suggests a position obtained through marriage, or perhaps artistic talent (the royal family's portrait painter?), or perhaps a high class lawyer, or something else Libran.
Based on the almost complete lack of challenging aspects to your south node and its ruler, it seems like this was a mostly easy life. However, Venus's position, in Pisces in the third house, helps clarify the situation. Third house indicates a situation where you had to live by your wits. In the genteel kind of society that the tenth house Libra picture paints, that would be a genteel kind of living by your wits. You were constantly having to flatter the right people, talk smoothly, subtly advance your position.
Pisces and Libra are both very easygoing, don't-rock-the-boat signs. Libra wants to keep the peace at all costs, and Pisces is the zodiac's shapeshifter, easily recreating itself to please others, to adapt to what others want or need. Having your south node and its ruler in those signs indicates that's the kind of person you were in the karmic past--a people pleaser, always ready to tell people what they wanted to hear and give them what they wanted. In Pisces in the third house, you were probably very good at using that skill to get what you wanted, but you could never get what you wanted directly, and you couldn't assert yourself directly.
The only aspect your Venus makes is a square to the AC/DC. Interestingly, Mars almost squares it, but not quite, it's just out of orb. That might indicate a minor detail of something or someone that crossed you--perhaps a rival for your social position--but it's not a major part of your karmic story. The square to the AC/DC indicates difficulty balancing self with relation to others. That this is a square indicates that you were aware of the problem, and probably uncomfortable with it, but never managed to resolve it.
Then you have one challenging aspect to your south node: opposition to the sun. Sun in hard aspect to the south node indicates a powerful person (or persons, or events) that overshadowed you, eclipsed you. Fourth house in this context most likely indicates family, and the sun being conjunct Jupiter indicates wealth, fortune. Aries adds the detail of this person being very forceful, and perhaps aggressive and controlling. That this is an opposition indicates that this person had complete power and control over you.
I'm reading the story like this: you were the daughter (or son) of a wealthy father, who controlled all the money and forced or coerced you into a socially and politically advantageous marriage. That marriage brought you high social status, but you never had any control over your own life. In the social circles you moved in, and probably within your marriage as well, you always had to flatter and cajole and play to the expectations of others in order to get anything. Probably, you had the same kind of relationship with your father. He controlled everything you had and doled it out at his whims.
Oppositions to the south node also represent what you wanted but was unattainable. In that past life, you wanted control over your own life. You wanted that powerful ego your father had. You wanted to be able to control your own money and relate to people on your own terms and decide how to live. That was denied you. So this time around, you came into the world determined to have all that.
Karmically, relationships are an area in which you need to set things right. That's indicated by Chiron being in your seventh house. Also, Mars, the ruler of your north node, is conjunct your DC, another indicator that relation to others is a key growth area for you.
However, setting things right in the relationship arena doesn't always mean having a long committed relationship. What it means is having relationships that meet your needs and are fair to the other person(s) involved. In your case, it looks like your main need is to redefine relationships on your own terms. As long as your own terms are compatible with the other person's, that's a reasonable and healthy thing to do.
