Hypothetical question

Sorry for the wall of text. Quick background on my situation — any input appreciated.

former employee took trade secrets. I've been dealing with this for about 12 weeks now and the situation isn't improving.

This involves software/code I developed over the past 26 months. I do have documentation proving my ownership and timeline.

Am I overthinking this or is this a real legal issue worth pursuing?
