desperately need advice

my boyfriend and i have sent each other some nudes from time to time for about 2 weeks now, today by accident i found out he had saved them all without my knowledge (using a snapsave app) and had kept the knowledge he had them a secret from me. a couple of days ago we discusssed screenshotting them and both agreed to that with the use of like a photo vault. but he did this from te first time onwards, he has been extremely good with his apologies and trying to talk to me and make it right, but ive asked for some space, despote not really wanting it. i just dont know what to do, how to act, i know i cant leave this relationship bc i love him too much, but what do i do and how should i continue to proceed? please help xxx
