I didn't know that there was a term for this.
Yes, it is possible to have this as an adult.
I have a good group of close long term friends ( around 6/7 of us). Literally, we all refer to each other as sisters, and they are all supportive, respectful, fun, trustworthy, honest, and educated. Every single one of these women are individuals whom I trust (they/we don't gossip/lie/talk about others behind their backs) and if one of us needs something/has an emergency, many(if not all) would drop everything in a second, to offer their help/support if need be.
So, speaking from personal experience, it is not impossible, but it just takes time and effort. One of the best decisions I've ever made was to be cognizant of who I hang with and choose my friends wisely, deciding to cut off any negative and toxic friendship(s) and holding onto/investing in those friendships I found worthwhile.
imo, nothing can replace that bond of a strong women friendship.
