He's never been violent or even close to it. He is the most gentle, sensitive man I know. It's very hard to accept that it's the same person doing this.
OP, I am terribly sorry. The acceptance that the gentle man you thought you knew is in fact a sex offender must be one of the most acutely painful of experiences.
But a sex offender, he is. It saddens me such much that as women we are conditioned to question our own boundaries and even our own realities before we question the behaviour of men.
Abusers (yes, he is) would like us to think that consent is a grey area, that the boundaries surrounding it are 'fuzzy', that they are somehow unaware that their actions are distressing or how they are such a gross violation of trust.
Consent is, however, one of those few black-and-white issues in life around which the waters are not muddy, the lines are not blurred: they are a straight, clear line. Enthusiastic consent and agreement to all acts you participate in. (And yes, the objection 'does he have to get a signed contract beforehand' is as ludicrous as it's frivolous. Men KNOW when they are violating our consent. The fact that he doesn't think you know what he's doing is evidence enough of this).
Sharing your images would make this even worse, but even if he isn't that does not negate the seriousness of his photographing you without your knowledge. If I ever, just once, found recording or listening devices in my living areas, was photographed or filmed without my knowledge or consent, or woke from my sleep to find myself engaging in an act I'd been unable to consent to, I'd be gone. I would certainly never be persuaded to have sex with that man ever again. On those ground alone the relationship would be over.
I do know that reporting him will seem an incredible act to you at the moment, so do what you need to do. And the first thing you'll need to do is process this and realise what has actually happened to you.
You poor woman. I'm so sorry
