@activemom,
you've got a couple of separate things going on
a personal relationship
a business deal
__
seems like they got muddled up together. you're going to have to split them apart as best you can.
1. forward his password. no commentary.
2. ask for an itemized invoice if you don't already have it.
sort the business bit out.
if that goes well, think long and hard about doing business with a romantic partner in the future.
I don't recommend it.
