Is what I did insecure?

Okay so I reposted a video on my tt about thinking that there’s another boy in all of this. Also I kinda think my girl’s gonna ghost me but that’s only because I don’t fully trust her yet, she saw the repost and she asked me why. I told her that I have weird gut feeling and I don’t certainly think that she will ghost me, she then asked me about my weird gut feeling and I told her that "Idk know how to explain it perfectly, but I’m still building trust with you. I’ve been hurt before, so sometimes I get a weird gut feeling even when I don’t have concrete evidence. I’m trying not to judge you unfairly. Basically I usually get a weird feeling when I’m trying to put my trust in someone." I also told her that I sometimes overthink stuff in my head because she’s someone I care about.
She told me that she understands. But I feel like I slipped up by being vulnerable with her, I’m really concerned about seeming insecure to her. Is what I did insecure or not?
