Has my guy friend been talking about me? if so why?

I noticed that my homegirl who is also friends with my guy friend knows a lot about me I used to share a lot of stuff on my instagram page about my narcissistic ex there was this one time I posted on my story of being at the hospital he seen my story and told my friend because she asked me if I was ok and I only have her on Snapchat, so the only way she knew I was at the hospital was because my homie told her then when I got out the hospital he seen my story and texted me and ask me what had happen? I replied back and explain things to him, then a few months later I start it posting about my narcissistic ex how I developed trust issues I also feel on edge now when it comes to meeting new people and I remember telling my female friend few things but not how I felt about meeting new people, yesterday I went to a concert and another guy friend of hers came with us but she had to tell me that this guy friend of hers is just like our homie that’s chill as if she knew that I have trust issues as if she knew that I felt on edge when it came to meeting new people.
