Question: Anything in my chart point to why I always feel the need to make myself the center or someone’s world? I’ll make this question more specific to romantic situations, but it doesn’t matter how into the person I am initially (like there could be almost no feelings) I always find myself needing to be…
Astrology perspective:

I would guess it’s a mixture of Scorpio and Sagittarius energy.
Moon is in conjunction with Jupiter in the 8th House; Sun is in conjunction with Pluto in Sagittarius; South Node is in Scorpio. So not only your unconscious idea of feeling safe (Moon) is about being the center of someone else’s world (Sagittarius – informal leadership) no matter what (Scorpio), but your identity and self-esteem (Sun) need some manipulation (Scorpio) to become the center of the life (Sagittarius).
Your idea of how relationships work (Venus) and how your mind works (Mercury) are also influenced by Sagittarius and Scorpio through the aspects with the Moon-Jupiter conjunction.
Moon in your chart is the ruler of the 7th House, so it shows what your relationships are like.
Saturn on the cusp of the 7th House makes patterns in relationships stable and also may make you feel that relationships are core that you can hold onto, they are your anchor and foundation. That’s why you want control over them to feel you’re grounded.
