Friend Dilema ; Bachelorette Party Invites

Hi,
So I have a dilema and would love some outside points of views
For a long time I had two guy best friends, who also happen to be lifetime best friends with each other. For the purpose of this conversation they will be G & C In the past year and a half I have lost touch with G, not like he isn’t friends with me on social media but we simply stopped reaching out to each other. On the other hand I have gotten closer to C. When I got engaged in January it didn’t even cross my mind to call G and let him know, but C was aware that it was happening beforehand.
When it came to our guests list, we weren’t sure if we should invite G & his long term partner. But when it came to C I had no doubts that I wanted him at my wedding, I asked him to be my Man of Honor.
It seems that decision has caused some tension between them and my other friends who know him. I don’t want to cause my bridal party extra stress, I know they have my back, but they won’t tell me how the conversations are going because they don’t want me to worry about that. But I know there is tension because of things that have been mentioned in passing.
My issue is that C will be the only straight man at the bachelorette party. Should I invite G and other people to the bachelorette even if they aren’t invited to the wedding?
