Hello carvillem.
Thank you for using Apple Support Communities. There are certain scenarios where you might not be able to someone to a group message. Click here for details: Add and remove people in group text messages on your iPhone or iPad - Apple Support
1.) You can only add someone to a group message if they're using an Apple device. If you want to add someone to a group message but they're using a non-Apple device, you need to create a new group message. That message will use SMS/MMS by default since someone is using a non-Apple device.
2.) You can only add someone to a group message that already includes three or more people. You can't add someone to a messages conversation that you're already having with just one other person.
Just in case, the following resource has more details on how to properly set up and send group messages:

We hope this information is helpful. Cheers.
