If you’re an Arrested Development fan (if you’re not, shame on you!) you’ve certainly had a good laugh or three at Tobias Funke, the never-nude. In sitcom humor, the idea of a grown man who refuses to be naked is funny but, let me tell you, in real life it is not. In fact, it’s near tragic.

My first boyfriend was, well, my first everything. He certainly wouldn’t have won a Brad Pitt lookalike contest, in fact, he probably wouldn’t have even been invited to compete, but he was funny and that’s how he hooked me. We were both in high school, but he had more bedroom experience than I did so I always let him take the lead, which is why I never questioned his insistence on leaving on his undershirt. That’s right, he’d take off his polo or his long-sleeve t-shirt but never that white Hanes V-neck. I always thought he kept it on just in case the parents returned home early. Now that I look back on it, I see how absurd that was.

As Erin already pointed out, there will be some point in your career as a twentysomething when someone will break your heart. There’s also a chance you’ll break someone’s heart. Either way, there’s a good chance that someone will be your roommate, making cutting ties an even bigger bitch than usual. Here are the dos and don’ts of breaking up with your live-in boyfriend from girls who’ve done it.
