Articles or books to identity my feelings of isolation around husbands female friend

Hi, my husband has had a female friend in his life for a few years now. He met her through his work 10 years after we’ve been married.
She has never been inclusive of me or interested in getting to know me at all, despite my efforts. I’m fact she muted me on social media apparently because she struggles with “jealousy” she told my husband. It got to a point of being so uncomfortable that now my husband just spends one on one time with her and we don’t attempt group get together anymore. I don’t feel like I know or trust this woman and she doesn’t respect that this is my husband.
This is the only person/friend my husband hangs out with other than me so it is quite often (one day each weekend- or every other weekend). Plus phone chats and texts. He uses the excuse that they are talking about work. Which is hard for me to hear because my husband barely talks to me about his work and I’m always trying to support him. It makes me feel detached from this major part of his life.

When they spend time together I always feel like it puts a huge dent in my relationship. I feel like my husband enters this foreign world and I feel isolated because their friendship is not a friend of our marriage.

My husband doesn’t get this or my perspective at all – In fact he gets defensive and we fight if I express anxiety or feelings of detachment when he tells me they are hanging out. He says I’m not his mom and he isn’t going to stop being her friend.

Does anyone have an article or book that might capture this isolation and detachment Im feeling so I can gain some language to help him understand? I can’t imagine continuing life with him while he has this woman best friend in his life that I don’t have any sort of relationship with at all.
