With DC in Libra and Northnode in Scorpio on your 7th you want a committed relationship with whom you can develop a deep bond with that will consume you and transform you.With Venus in Taurus conjunct Southnode and Mars in Leo I would say you are possessive, protective and jealous but your venus square Uranus and Sun in Gemini keep that side of you in check making you open minded and letting your loved ones enjoy their space.
In your case is good you have venus square uranus as it helps balance out other placements in your chart that would make you perhaps too possessive.
Venus square uranus does not automatically mean fear of commitment but with southnode in the 1st in some level there is fear of commitment bc you are use to being independent and on your own however you are meant to be in relationships in this life so you can hone your relationship skills which you lack and learn to use power in relationships so you have a true partnership of equals which means allowing yourself to be vulnerable and letting the other take the lead and be in control sometimes and you being the one in control at others without abusing your power.
Its a lesson of experiencing love without manipulating or controlling it, a lesson of surrender and relinquishing control to the other without giving up all your control either and finding that balance.
