I let my boyfriend spend $18,000 preparing for a baby I knew wasn’t his because I wanted to see if he’d actually be a good father. We’d been together for five years, and he’d been begging me to have a baby with him for the last two. I kept telling him I wasn’t ready. The truth was, I wasn’t sure I wanted a child with him. He was loving, but he was also comfortable letting me handle most of the responsibilities in our relationship. Then I got pregnant after sleeping with my ex. My boyfriend was overjoyed when I told him. He immediately started talking about being a father, bought a crib, paid for prenatal appointments, and even moved us into a bigger apartment. I watched him do all of this and made a decision. I wasn’t going to tell him the baby might not be his until I knew whether he’d make a good father. For months, he treated me like a queen. He cooked, cleaned, attended appointments, and saved money for our daughter. I told myself that if he was willing to do all that, maybe I could finally love him the way he deserved. Then the baby was born. She looked nothing like him. His mother noticed first and made a joke about it. He laughed, but later that night, he asked me if there was any chance another man could be the father. I told him he was being insecure. He apologized. I let him apologize.
