Did my husband do the right thing? Updated 12/30

My husband has a female friend who he has been pretty close with since childhood. She’s always been respectful of our relationship, I genuinely like her, and thought she liked me too. We have never had any issues as far as I know and I considered her my friend as well. She just got married this past Friday and specifically invited my husband, not me. The invite said “sorry for the inconvenience but no plus one please” so there was no way to misinterpret it. The invite was his name only. Initially he wasn’t going to go without me but I told him it was fine, they must have a good reason and she’s a close friend. We assumed they were holding a smaller, budget friendly wedding. He went to the reception, not the ceremony because there was a conflict with his work schedule and when he got there he immediately noticed that ALL of their mutual friends husbands and wives were present as well. One of his buddies asked where I was and he said the invitation specifically stated no plus one. His friend said that was weird because his invitation was made out to both him and his wife AND there was a spot to write in a plus one if they wanted. My husband asked a couple other friends and they all said the same. He was irritated and called me saying he wanted to confront her because he wanted to know why I wasn’t invited and I told him it could wait and to not cause a scene at their wedding. He said he wanted to come home because he was sick of seeing everyone dancing and enjoying the evening with their significant others while I wasn’t there with him. I told him to at least tell the bride and groom he was leaving and congratulate them once again. Well he got home and apparently the groom asked where I was as well and she played along, when my husband mentioned the invitation the groom looked confused and she got all defensive and nervous saying there must have been a mistake. He congratulated them and left. On his way home he got a text from her saying she just wanted her wedding night to be perfect and she wanted the “old” (my husband’s name) and that she felt that I held him back and made him unhappy. He told her I was his wife, his better half, and that if she couldn’t accept me then he couldn’t be friends with her anymore. I told him I appreciated him supporting me. One of their mutual friends reached out and said what she did was wrong but asked him if removing her from his life was a bit much and now both of us are questioning it too. My husband wants my input and I don’t really know what to tell him because I’m at a loss too. I don’t know what she means by “I hold him back” because I have always supported him and whatever he wants to do and I have never tried to change anything about him as he’s perfect to me the way he is. I didn’t realize she disliked me this much and I also question if she’s maybe jealous of me? Overall I’m hurt and feel like I’ve been lied to the past 7 years. I think I will tell him how I feel blindsided by this and that his judgment is most important but I thought I’d come here for advice.

Update —

I didn’t plan on following up but I also didn’t plan on this post getting so much attention. I just want to say thank you all for helping us realize my husband’s decision was in fact the right one. He’s had the sweetest smile on his face hearing all the nice comments towards how he handled things. I don’t have much else to say at this point. He texted her again and told her he couldn’t be friends with someone who showed me so much disrespect and has removed her on everything. I’m not sure how things within the friend group will be now that they aren’t on speaking terms but my husband said he will figure that out when the time comes. Apparently her new husband is questioning her feelings for him as well as my husband but we aren’t getting involved in their personal life so that’s all I know. I am so grateful to have such a supportive husband and I made sure I thanked him well if you know what I mean, haha. I am also thankful that the majority of his/our friends had my back as well. Thanks again everyone.
