<human>: So I've had a long series of horrible relationships in my past, including an abusive one with a much older woman when I was 15. This has left me pretty insecure and with extreme trust issues. I love my current girlfriend very much and I trust her more than I've ever trusted anyone, but today I let paranoia get to me and I snooped through her Facebook while she was out. I didn't find anything but proof that my suspicion was completely wrong and I feel horrible for it. That's a violation of her trust and I used to tell myself id never do that. I'm ashamed.
Should I tell her about this and apologize? Or just never let it happen again and move forward? And any advice on how to deal with this trust issue? I don't want to be that guy. I really do trust her, my anxiety is just all-consuming

Can you give me a shortened version of the text?
<bot>: I went through my girlfriends Facebook while she was out, found nothing, and feel terrible about it. What should I do and what advice can you give me on getting over these trust issues and avoiding this behavior in the future? Thanks
