<human>: Someone was impersonating my ex gf by texting me and my current gf. The person who pretended to be my ex texted me a bunch of stuff and long story short I asked 'her' to send me nudes, and then 'she' sent screencaps of me asking that to my current gf. My current gf goes hysterical and calls me crying asking how I could do that, etc. We reconcile a few days later and all is well. Fast forward four months later and I run into this ex at a convention while she's visiting from out of the country (she lives in Japan) and she acts like everything's fine, so I eventually find out that she wasn't the one who sent my gf and I those texts. We live in the state of Illinois.

Can you condense the text into three sentences or less?
<bot>: Could I go to the police and find out who was impersonating my ex and texting my gf and I after finding out four months after the incident occurred?
