He has to stay on his side of the bed—no cuddling in the middle of the night. And if I’m not feeling in the mood to have company, he has to leave without argument. The first month, that happened as often as not. But I haven’t asked him to leave in weeks. The truth is, I’m growing to enjoy sharing a bed with him. On the nights he’s at his own apartment, I look at the empty spot on what has now become his side of the bed (the left), and I feel an ache in my chest.
