Can you dear brother give some affirmation for this with the rune or suggestion for more runes? fixing relationships with family or loved ones?
Wunjo is broadly healing and restorative of positive connections and can be used in most situations. Gebo is specific to energy exchange, like between lovers. Berkano promotes nurturing and is best for families. Ehwaz is a rune associated with friendships.
Obviously, we can still mix these runes between their associated relationships, but those are just the "traditional rulerships". If you have poor communication with a lover, but lots of love, then it would be more appropriate to use Ehwaz and Ansuz, rather than more Gebo. This is just one example of factors to consider.
Anyway, for a simple example of a working, take Wunjo and Gebo, chant each to x40, then affirm: "My relationship with [person/family] has been permanently improved, in the most positive manner." x5
Visualize the energy acting upon the astral bonds and see the connection strengthening, as any weak spots have been enhanced and improved. You can visualize it glowing with energy, now having been permanently improved. Also visualize yourself and the other people as more prosperous because of the working.
