Hi Mijape
In general a Uranus to inner planet contact in synastry is going to indicate freedom/commitment and intimacy dilemmas. A Double Whammy means that both partners will have issues with settling down, making a commitment, opening up to a partner. One person may commit but the other person may back away. Then they may switch roles.
A Uranus to Sun contact indicate can indicate one or more of the following:
Close, but platonic
Both value freedom
Strongly attracted, but from different walks of life
Relationship different form the norm, or defy societal expectations (may be unable to marry)
There may be issues about lack of reliability or one partner letting down the other
Intense relationship but transitory
Impersonal
A Uranus/Moon with easier aspects means a more subtle manifestation of Uranus synastry.
The Moon indicates an emotional emphasis regarding the Uranus influences noted above.
This indicates that the couple has difficulty emotionally connecting to each other, individuality may be more important than the partnership. Dependency and independence may be issues.
There may be a feeling of “I don’t need love”.
One partner may be unavailable.
