Am I too detailed?

My girlfriend said I should see a therapist because of my jealousy. I don’t really consider myself that type and never really was in my previous relationships. But in this one I can confirm that I have a issue.

We are together for 6 month and we are living together. I don’t know many of her friends really but her family. I sometimes feel like I’m left in the dark a bit I’m general because she don’t open up to me so much but says it’s her normal behaviour.

Today she told me she watched a podcast about a very pretty fitness influencer that was talking bad about women and the girls compared him to a Stone Age person. She mentioned his name and I have some kind of photographic memory so i recall the name with a picture in my head from her Instagram.

When she was then getting ready for work I checked if I’m right (not sure if I should do this but I did) I saw her I stages followers and saw he follows her private account with around 400 followers she calls her friends. The guy has under 3000 followers and no link in his Insta bio for promotions nothing. He not really a influencer to me more a "friend" of her. She didn’t mention this and I also didn’t. Btw he likes her pictures also…

Now when she came from the bathroom I asked her why she told me that story and had to point out the guy is very pretty. I consider myself good looking I’m very tall but more the skinny kind and not a bodybuilder guy. So am I here wrong for thinking she should be more open and say she knows him or am I tripping?

I did point out things before where I was clearly wrong and I don’t want to start a discussion with her because she usually dont listen then. If she thinks I’m too jealous she stops listening.

i don’t like her Instagram page since recently she uploaded a picture with us in it and then I started to see who comments it and who likes it. Then she pointed me out that she looses followers from this. Then I saw some of her followers and majority is guys following her back mostly no business pages and very little other girls. I don’t like the idea that this is private and it’s like 200 guys that also live in this city or area mostly. I’m not feeling good about this and then her talking about one of them like he is famous but he is in her followers.

Please help 🫶
