@pattyinal While I cannot tell you what to do, or what to say, let me share with you the way I handled an awkward conversation. If this is a group for your husband and his health issues, you could say that you would like to know what this group is all about and see if it is something that you could get more information about his situation. Take him with you to that group. Then, when he sees that it is for his condition and not necessarily for more information for you, you could say, "oh wow look at these people and what they are working on! I bet something like this could be beneficial for you too! What do you say? Would you like to try it?" This way it is looking like a happy surprise. And don't forget about taking care of yourself, too! It's tough to be in caregiver mode. I hope you will let us know what happens.
