<human>: Can you provide a brief rundown of the text in within 3 sentences?

She broke up with me after 1.5 years. We were rocky for about three weeks. I had made a tinder account during this time. We got back together. I didn't delete the app until I knew we would be stable again and not break up for real. Well, about a week after I deleted it  coworker of hers showed her a screenshot of my profile. She's livid and idk how to explain to her it was just an ego boost. She doesn't believe me and thinks I downloaded it while we were still dating. I didn't meet up or even offer to meetup with anyone on the app. I can't prove this because I had deleted it a week before she was shown the screenshot.
<bot>: gf's coworker showed her a screenshot of my already deleted tinder account shortly after we got back together. Idk how to make her know it was no big deal to me.
