But the critical truths—that we aren’t really in love, never have been, and its absence troubles me—don’t seem to come in little drops of awareness. They’re suddenly there, in stark black and white, shouting This Relationship Is So Very Over every time we smile politely as we shift around each other at the bathroom sink.

I’m sick over it. I’m desperate to find the best way out. Unfortunately, I worry that Sean’s chief reaction will be disappointment. I am as convenient a lover to him as he is to me; but in his case he may not need more: he has the love of his life already, in the form of a six-year-old daughter.

A good start seems to be to make sure I can afford to live on my own in the city. I take a rare vacation day and drive to El Cerrito to do something I’ve been putting off for months: meeting with my financial adviser. Daisy Milligan is Dad’s old finance whiz, and I kept her more out of sentimentality and laziness than any particular knowledge about her skill.

That said, though she’s approaching seventy, she barely needs to refer to my file while lecturing me on what I have in my trust (enough to cover home repairs and taxes, but not much more) and why I should sell one of my houses (I need a retirement account more than I need two properties). I don’t dare mention that I’m living in San Francisco and not even making rental income from the Berkeley house.

I hate talking about money. I hate even more seeing how badly I need to get organized financially. Afterward, I’m sort of high-strung and buzzy, and when Elliot texts asking how my day is going, and I tell him I’m on his side of the bay . . . meeting up seems like a pretty obvious choice.

He suggests Fatapple’s in Berkeley, having no idea how close that is to my house. So instead I suggest we meet at the top of the Berkeley hills, in Tilden Park, at the entrance to the Wildcat Creek Trail.

I get there before he does, and outside my car I pull my fleece higher on my neck to battle the wind. The fog rolls in over the hills, making it look like the gray horizon is sinking down into the valley, an inch at a time.

I love Tilden, and have so many memories of coming up here with Mom, riding the ponies, feeding the cows at the Little Farm. Dad and I would come nearly every weekend after Mom died to feed the ducks at the pond. We’d sit in silence, tossing torn-off pieces of bread into the water, and watch the ducks snatch them up, quacking at one another competitively.

The nostalgia of Tilden seems to mix with the nostalgia of Elliot and forms a potent brew in my blood, tearing through me. Even though he and I have never been here together, it feels like we have. It feels like he’s part of my nuclei, entwined with my DNA.
