DEAR HARRIETTE: My girlfriend and I decided to break up. It was mutual. We both had our own grievances, and, in my opinion, we’d hit our peak. I don’t think staying together any longer would’ve made a great difference for either of us. Things got complicated because we lived together in a two-bedroom apartment. To be amicable, I offered to take the guest bedroom and stay out of her hair until our lease was up. She blew up and said she’d rather us not live together after breaking up. She said one month should be enough time for me to find a new place. For context, I’ve paid our full rent, happily, for the past year and a half, so yes, I think her suggestion is ludicrous and unfair. I feel betrayed. How do I reason with someone like this? -- Ultimatum
DEAR ULTIMATUM: It’s time for you to develop a backbone. Kindly but firmly tell your ex that she has two choices: She can move out now or as soon as she can, or she can be OK with you being in the guest room. Remind her that you have paid for your home the entire time the two of you have lived there. Yes, you did it happily, but now that you are parting ways, you are unwilling to inconvenience yourself due to her discomfort with the living situation. Things might get hostile for a bit, but she needs to understand that you are not a pushover.
