So yesterday was the memorial for Christ, the one thing…

So yesterday was the memorial for Christ, the one thing Jehovah’s witnesses celebrate, the death of Jesus.
(My husband was raised a witness but doesn’t follow anything besides no holidays and the memorial. I’m trying to show them all who Jesus really is.)
So yesterday we did the memorial in our home(just my husband and I and our children), and I thought it’s all ok that I pass on the bread and wine also because of Romans 14, I didn’t want to make them stumble, but I had the plan to eat and drink in private, just the Lord and I. Anyway, I was just curious as to what all these witnesses do with the “body of Christ and blood of Christ” after the memorial, since they don’t partake of the emblems, only pass…
A life long witness (my mother in law) said to throw it in the trash… ???? I asked what the congregations do after the service and she said the same. They throw it out ?.
This has made me sick all day and I’m just at a loss…
Has anybody heard of this before? What would you say? Scripture references?
She said it has no meaning the next day so it’s ok and it’s showing a love for Jesus…
Looking forward to our study tomorrow if they don’t cancel (because I let them know there is no way I’m throwing it away, to me that is complete disrespect). Just at a loss for words and not sure if I’m more disgusted or heartbroken ?
