Tricky situation could use some advice

Hi there,

My girlfriend is kind of in a tricky situation. Essentially she purchased multiple ethereum a few years ago and kept it in some sort of harddrive wallet (apologies btw if I sound retarded, I dont know much about crypto).

This wallet was saved on her ex's computer. At some point they broke up and he held onto it. (And also stole her turtle like a dick).

Just curious, is there a way she could get this back? I think the total amount could be worth $5000 today.

She doesn't have access to the computer and her ex is a total CHODE.(wouldnt give her turtle back).

She's worried if she contacts him and gives him her pw to get in, that he is going to just ADIOS and ghost her.
