I am sure you notice when you like people instantly or dislike them instantly. Sometimes, people dislike you for no seeming reason. There is an answer and it is found in the charts. Of course, you knew that! Let’s explore this question astrologically.
1. Mars Conjunct the Moon
The Mars persons feels dislike for the Moon person. The Moon person, likely, does not understand why. It seems as if the Moon person will try to make it better, but the attempts, likely, will fail. In time, the nastiness seems to escalate. Hence, the Moon person should not try. The Moon person should muster his strength against the attacks. If the Moon person is gone, he can make the Mars person retreat. That is the best outcome in this situation.
2. Moon square Moon
This may not be instant dislike. This would, more so, be dislike over time. Hence, there may be great emotional differences which are impossible to bridge, but these may not surface until the relationship becomes more serious. I think one could intuit them prior to this, but one may dismiss them.
3.Moon Oppose Moon
This aspect is more of a small kind of back biting. These two can be friends and long term friends, but there may be an undertone of tension. This aspect may not kill a marriage. I would not like it, myself, in a marriage partner. I hate any kind of back biting dissension. I like good aspects to the Moon for marriage. The Moon is one’s heart. One’s heart is very sensitive.
4. Venus Square Venus
This aspect makes for very different tastes and likes. For example, one person may like opera and the other may like rap. One person may dress like a preppy and the other like a goth. One may like simple furniture and the other may like heavy, dark woods and large furniture pieces. Also, there may be a dislike of the mannerisms of the other. One may think the other dresses in a garish or unrefined way, for example. One may not like how the other one speaks. I think one could be in a relationship with this aspect, if the Moons were very good, but the tastes would, always, be an issue.
5. Nessus Conjunct the IC
The IC is one of the most sensitive points on the chart. Nessus is the asteroid of abuse. I would not like Nessus conjunct ANYTHING that was sensitive in my chart. If one has to do with a Nessu, one wants to use the strongest part of one’s chart, not one of the weakest.
