Hi learner,
There are 2 flower of romance direction in our chart but some have only one as both might be the same. So beside checking on the year pillar you also need to check on the day pillar for the 2nd flower of romance. Since one of the flower of romance direction of your husband is in the West2 Rooster direction, you shall remove any water feature, empty vase and love symbol in that direction.
For the rooster with amethyst, you can place it in the rooster direction West2 and please let us know the outcome.
I think there is also a need to check your bazi and the feng shui of your house.
