Both zip files are showing empty packages. It appears that you used Clean Installer to remove a piece of the content that you made her with and then just saved it. What you need to do is re-package her, Then if you need to remove something from the Sims2Pack file you can but this time click the save as button and give it a new name, just add a 2 to the name. After it saves look at it with Clean installer and scroll all the way acroos to make sure it doesn't list empty packages. That should fix it.
When I download the file ib the first post and I open it up with Clean installer all the package file inside list as empty packages. It looks like you used clean installer to remove some of the content and then resaved it as the same sims2pack after you removed them.
I tried that way and they switched off as soon as I editted him, But I moved them onto a lot and worked their relationship up to the in love stage and had him (elder Male) propose to adult female, she accepted and I then had him click on the standard wedding arch and choose get married. They then went through the wedding animations and now they are showing the married/joined flag on their relationship thumbnails.
