Don't ask, don't tell (DADT)

Don't ask, don't tell is a configuration in which a couple agrees that each may have outside sexual or romantic experiences, but that those experiences are kept off the table at home: you don't ask your partner about theirs, and you don't tell them about yours. The agreement deliberately walls off the outside activity from the shared relationship, on the theory that what isn't known can't hurt. It's most common among couples opening up who find the emotional reality of hearing details too much to manage.

DADT has real appeal for some people. It can lower the acute pain of imagining a partner with someone else by simply removing the information, and it preserves a clean, undisturbed surface for the primary relationship. For couples whose distress is specifically about the details rather than the fact, it can feel like a workable compromise.

But it sits in tension with the consent and honesty that define ethical non-monogamy, and most experienced practitioners treat it cautiously. The biggest problem is sexual health: if you don't tell, your partner can't make informed decisions about their own risk, which undermines the disclosure that safer-sex agreements depend on. It can also shade into a form of plausible deniability that's hard to distinguish from cheating, and it removes the communication channel through which problems would normally surface.

Where DADT works best is as a narrow, explicit agreement with carve-outs for the things that genuinely affect both partners — sexual-health status above all — rather than a blanket silence. Where it works worst is as a way to avoid the harder work of building the emotional capacity to know about and accept a partner's other relationships.
