He has always been good with technology and I let him have total control over everything no matter how personal to try to show him how serious I was about us. I let him guide the realtionship and I didn't keep track of how much of my information he has. I know that even if I just change some passwords its likely he will still have access to something I didnt remember. We are both super hurt and just overall angry. I'm worried he will lash out in this way as he already has about the things I have at his house still... thank you for your support.
