I’ve been avoiding PC due to being very easily irritated. But thought I’d pop in quickly.

WC, I’m so sorry to read of your circumstances. Sending many hugs your way.
I agree with the person that suggested you take your computer to the police. The reason is that it may not be as simple as your husband wanting to hurt you. A forensic examination may reveal what if anything your H may have tried to hide (that he suddenly felt he had to wipe the computer). A forensic exam should recover your photos.
My hubby works in IT and has had to over the years conduct many computer forensic examinations. Without fail everyone who tried to wipe their computers clean were hiding something.
