If you really love him, it's not the guy, it's the sex. If he makes your workdays uncomfortable with inappropriate advances, if he exacts retribution because you cut it off, if he shares those photos with co-workers, or if he blocks your advancement, that's harassment. If not, brush up on the info (or call one of the hotlines) here. What doesn't kill a relationship can make it stronger, I suppose. ) The most important thing is that you end the behavior and figure out why you're doing these self-destructive things rather than facing your problems head-on.
So, if you haven't already, tell him you'd like to try something new. As for your boyfriend, you've only got two choices, don't you? On that note, here's a second opinion from a few of my guy friends: Lie.
I’ve a confession that may or may not surprise you: I am two months shy of 24 and I got together with my boyfriend at the tender age of 14, during the extremely heady days of peak emo.
Now we are poor creative types; he’s an animator and I’m a writer, so we spend our time figuring out how we’re going to eat.
You don't have to tell him you're "bored" — in fact, don't. My paradoxical pals say they'd like to know if a girlfriend was sexting (even if it was just in good fun), but they also say that they'd freak out if their girlfriends did this, and probably wouldn't be able to forgive them — even if they, themselves, would totally love to be on the receiving side of some colleague's hot pictures. It's also a pragmatic (unethical) reason (excuse) for lying.
But you could tell him about all those things you fantasize about doing with someone else — and then try them out with the guy you love. The cost of lying is the guilt you'll carry and the secrets you'll keep, both of which may push you and your boyfriend further apart.
And think about whether this is really just about sex. They're way more likely to pick up on the slightest hint of a flirtation than a polite brush-off. Since he's your superior, I'd recommend doubling up with an email so there's proof that you broke it off, in case he harasses you later. In a way, Snapchat is just an exaggerated digital version of the flirting people do every day. Then he's going to be jealous when you're at work and suspicious when you come home late.
