Would you be pissed if your OH looked at your mail in this situation?

Recently my OH was cycling home from mine in the dark. He had no lights, no helmet, and was dressed all in black. It was extremely windy outside and obviously I was worried. HE promised he'd call when he got in, but he never did. I hardly slept all night, I tend to worry about stupid things anyway, so I sent him an email reminding him to call me. I also text his mum as he is staying there until we move away together in September. The next morning when I turned my laptop on and saw he was logged into his google mail, so instinctively I looked on his email to see if he had read the message I sent him. I have NEVER looked at his email before as there was never a need for it.

He has recently been very lax in applying for jobs, so I was alarmed by all the notifications of new jobs from the NHS that had been sent to him. I scrolled down, and was pretty shocked to see the website 'adultwork' in his email. Usually I would have just presumed it was something to do with his job, but my ex boyfriend was on it once and used it to have cybersex with girls (that ended badly).

I do and I don't feel bad for looking at his mail, I mean, he should've called like he promised, and he should have been applying for jobs. It effects me too! We are moving together, I can't afford to pay the rent by myself!!

So anyway, this adult work site, turns out he has been paying for access to girls profiles, girls that are in his area. That majorly rang alarm bells! He has a thing for redheads, and they all happen to be redheads. I'm mixed race and brunette so you can imagine how that makes me feel.

What should I do? I am so worried that the issue of me looking at his mail will be made to seem worse than the fact that he is on an escorting website. Is it bad I looked at his mail?

What would you do? I'm so upset that he's looking at girls in his area. Stuck here guys!
