Q: I’m a thirtysomething straight woman married for 16 years. Eighteen months ago, I met a man and there was an immediate attraction. For the first 15 months of our relationship, I was his primary sexual and intimate partner, as both sex and intimacy were lacking in his marriage. (My husband knew of the relationship from the start and is accepting for the most part.) After my lover’s wife found out about me, she suddenly became very responsive to my lover’s sexual and emotional needs. My lover has told his wife that he will not let me go. He has also told me that he is not willing to let his wife go. She isn’t happy about being in a triad relationship, but she allows him to continue seeing me with limitations. I am no longer his primary sex partner, and I have been relegated to the back seat. He claims to love us both, yet his wife and I both struggle knowing the other exists. Recently while out shopping, my lover asked me to help him pick out a Christmas gift for his wife. I got upset because I am in love with him, and I have made him my priority (over my husband), but I am not his priority. I love this man and we feel we are soul mates. My lover has said that if we fall apart, he will have to find a new secondary partner because his wife can never give him the soulful fulfillment he needs. Should I continue in this relationship? —Soul Mate Avoids Choice Knowingly

Calling your lover’s bluff—ending a relationship that, in its current form, brings you no joy—is your only hope of having this guy to yourself. But the likelier outcome is that you’ll be left alone (with, um, your husband).

But there are exceptions to every rule, DUMP, and I think your case qualifies. As with many exceptions to many rules, your exception honors the spirit of the rule itself. Both reasons I cite for breaking up with someone promptly—to spare your soon-to-be ex’s feelings, to get out of the way of your soon-to-be ex’s future—are about being considerate of your soon-to-be ex. And that’s just what you’re doing: You want to end this relationship now, but you’re going to wait six months because you don’t want to derail your soon-to-be ex-girlfriend’s education or career prospects. So out of consideration for her, DUMP, you should coast for a bit longer.   v
