When you KNOW you're being irrational...

I am a single woman, mother to a 20 month old, living with my ex (his father) because while we agree our relationship is a big fat fail, we want to provide a united family for our sweet boy. Most of the time we are actually BFFs. About 5 percent of the time we fight because we communicate so differently and things just explode. Aaaand we still have sex once or twice a month, mostly just to satisfy urges. Neither one of us has anyone else around. My problem is that I REALLY want another baby. And I really want him to be the father. Our son is BEAUTIFUL (per the opinion of practically a stranger per day) and sweet and smart and perfect. HE does not want any more children. Ever. Hell, he didn't want Jonathan. Now he adores him though. Even though he doesn't want children he won't get a vasectomy and doesn't like condoms, which is fine bc I hate them. I don't use any birth control aside from spermicide.
