Moon Opposition Sun love Synastry ~ Reworking Expectations
The Moon is the most important 'planet' in relationships. The Moon represents deep security needs, and it is difficult to be with with someone who does not offer us what our Moon needs. Positive Moon compatibility will show two people who feel "at home" with one another, and instinctively care for one another. It's like being family. That's why it's the most important planet in synastry. If you want to spend the rest of your life sleeping in the same bed as someone else, you obviously need to feel like family to one another.
Moon Opposition Sun
A Moon opposition Sun aspect necessitates a reworking of your relationship expectations. Differences in background, thinking, temperament, and approach to relationships attract you together and then repulse you in what can become a repeating cycle. You may have a frustrating time trying to get your emotional needs met.
