44F Looking for a calm and deep platonic connection / true friend

Hello, entering a mature stage of life, I’ve come to realize that finding a kindred spirit to fully share all of life's ups and downs is incredibly difficult. I am a 44-year-old woman, currently enjoying a stable life with my family and children. I see myself as someone with a mature mindset, a rich worldview, and a deep appreciation for meaningful connections. Right now, I want to dedicate my time and mental energy to building a genuine, long-term friendship with just one person.

I don’t mind whether you are single or married. I am simply looking for a companion who shares a similar lifestyle and values:

Personality: Calm, mature, a good listener, and someone who respects mutual privacy.

Background: Well-educated, with a stable career and job.
Lifestyle: Knows how to take care of themselves, both physically and mentally.

Regarding how we communicate:
I am looking for a sincere friendship with active interaction from both sides. Low-effort messages, a "take it or leave it" attitude, or leaving me waiting too long for a reply will prompt me to respectfully step away to avoid wasting your time. To ensure we are on the same wavelength, I’d love for us to ask each other a few brief questions to understand each other's mindset before diving deeper.
If you share the same level of seriousness and are looking for a kindred spirit to share life's perspectives with, please send me a message
