It was only meant to be every other weekend. But now I need him every night. As a single mom, a relationship was out of the question. So, we had an arrangement. The first rule: every other weekend. But that wasn't enough. The second rule: he can't meet my son. But he did, and they got along. The third rule: I won't fall in love. But I couldn't help it. The final rule: I'll never let anyone else break my heart. And now that rule is about to be broken too.
