Who know if you steal someone else device and what is the guaranty that you are femal? Anyway if this is real story then don't share anything with untrusted person, don't pay someone to recover your fund. Likely you may got many offer from scammer via your inbox. Just avoid them and ask them for public discussion here. Do be victim of scam again.
I don't see how, even if the OP has been cheated on, this warrants theft of who knows how much (or how little) funds in the first place...? Just because he/she is a supposed woman that is supposedly cheated on?
These seem like very seperate issues. I actually don't see any reason why we should help OP steal something that isn't his/hers.
Anyhow, if it's encrypted with a basic password and you don't know much about decryption tools, i doubt you'll get far anyway.
