I think every situation is different and its hard to make rules.
My wife is Buddhist (sort of) and grew up in a mixed religion culture (few Christians).
She is very supportive, comes to Sunday mass, puts the money on the plate (but not if she doesn’t agree with the homily or the priest ignores her when we come in the door).
Maybe once every 3 months I will miss Sunday mass and take her to the Temple here instead. (I don’t offer incence or kow tow before Buddha).
She doesn’t mind me going to daily mass.
Re Holy Week she doesn’t mind me going off to the Triduum events.
Why are you out every night during Holy Week - that sounds a bit over the top if it affects your partner?
She will come to the Triduum events if I ask her too but I know she finds it boring though she tries to hide it. Usually I don’t go on Thursday night but instead wash her feet in the lounge at home. That’s a highlight of the year for her. She even does mine.
She doesn’t go to the Good Friday liturgy because she got upset with the renewal of baptismal vows. My parish new age liberals reworded them and one of them went long the lines of “do you believe God is the source of your livelihood” or something. She thinks that is not right, she works very hard for her money and doesn’t see where God ever helped out there! If they hadn’t blown that one she may have been a Catholic by now

.
We pray together regularly each week as she has a great devotion to Mary as a person and she has no issue seeing her as a “heavenly” figure. Prayers of petition work very well.
She does the rosary and knows the hail mary off by heart.
When her mum died it was great solace to her that I participated in the main Buddhist rites such as they are. Everybody knows I am a committed Christian and that is fine. No incompatibilities from their side.
When we visit Europe she loves going to the old Churches, especially those with statues of Mary. She fell in love with Fatima, the singing, the feeling of holiness, the night processions with candles, the huge feastday crowds of praying pilgrims. She cannot wait to go to Lourdes.
In other words every mixed marriage is unique and must be adapted to the limits and opportunities for commonality that God offers. I believe that involves some reciprocity too.
We don’t have children so that makes it a bit easier, though she would have no issue with them being brought up Catholic so long as she could take them to the temple now and then.
