Libras and their surface level friendships

Im a libra with an aquarius moon and virgo rising. One of the things they say about libras is that we have surface level , superficial friendships/relationships. Which in my case I find true. After some self reflection I realised I dont build deep bonds with people. I dont really open up and let people know my deepest secrets, anxieties and fears. I listen and give advice if they do...but i am ok if they are not. I am very easily able to break a friendship , be it a month or a decade long and I dont fight for a friendship either. I can find another 🤷‍♀️ I am not lonely , it is not sad, it is not horrible...this is my normal. I dont have a big friend group but i dont have a "best friend" either. There are 3 girls i would call close friends and maybe 5 more i would call "associates"...we spend time in social settings but dont know much of each others life. And that is fine with me.

. Everyone is different. But i have been told i need to let people in and i need to open up...but my deepest feelings etc are for me only, not for anyone else. But any other libran who finds the same situation?
