If your partner knows, and has agreed, say so. The profile has a relationship status called Open relationship. Use it. An open relationship is not a softer way of writing married, and it is not a secret you are hoping they will forgive later. It means the person at home already knows there is someone else.
"I am in an open relationship, my partner knows, and I can meet for a drink in the evening" is a sentence someone can answer. "My husband knows" belongs in that sentence if a husband is the partner. A wife, or a partner you do not marry, is the same fact. Name the agreement. Do not name the person.
Do not choose Single, and do not choose Married and leave the agreement for the third message. Someone who wanted a secret will decline. Someone who wanted a single partner will decline. Both of those are the right outcome. If you are already married is the page for when they do not know. Thinking about an affair is the page for when you have not decided.
Say the limits the agreement actually has. Daytime only, someone of a particular gender, or staying out of your own town are different offers. If you can only meet in the daytime is the hour. Lesbian affairs, gay affairs, and bisexual affairs are the pages for who you want to meet.
You do not owe a stranger your partner's name, a photograph of them, or a move off the site to prove the agreement is real. A careful person can stay on Only Amour. Only Amour will never ask you for a fee to say that your partner knows, or to message someone who has read it.
