Delete Instagram.

Delete Twitter

Delete any distractions that might make her feel suspicious that you're eyeing anyone else. Social Media is probably the biggest culprit, especially with all the scammers out there with fake accounts, or impossibly perfect people with envious lives that are designed to capture your attention.

Silence any notifications if you have to, but she has to feel secure that there can not be anyone else.

I got distracted endlessly scrolling, and she thought I was thinking of someone else.

I used to get tons of notifications from Discord, that I ignored, but I thought she was okay with.

My aunts drop a bunch of links onto Line from their feeds, but it didn't sit right with her.

Anytime she gets that idea in her head, warranted or not, it will poison the relationship.

Keep talking to your friends of course through whatever means, FB messenger on your phone, not the main FB app. Texts only, etc, but make sure you can NEVER put yourself in the position where she doubts you, even for a second.

I know and you know that you're 100% dedicated to her, but if there's a tiny seed of doubt that permeates into her thoughts, it'll fester, and your relationship may not survive.

Mine didn't, I was being stupid and silly and it cost me the only meaningful relationship I may ever have.
