Consider if you will that pregnancy is a state of extreme vulnerability. The chances of being killed by a parter are astronomically higher for pregnant people… With the case of a lot of insurance, banking policies and economic infrastructure is designed to enable spouses to be treated as a single person any property you acquire is by default mutually owned meaning there’s all manner of control which can be exerted by a spouse. You cannot file taxes separately and kinship treats your spouse as both your automatic inheritor and a legal authority with power of attorney in the event of you are incapacitated so you have someone that you cannot fully escape from because of legal ties. If you fear for your life from someone any contact is too much.

Considering too that it relatively common for men who were not previously abusive to suddenly change their personality, dropping their masks abruptly once someone is essentially trapped into having their baby then not giving someone the ability to extracate themselves from this situation is creating incentive to put on these deceptions. In the matter of childbearing the risk is borne only by one partner. It would stand to reason that if a non bearing partner causes an undue increase in the risks during the most vulnerable stages of pregnancy that they default on both their responsibilities and privileges as a parent.

Critically in a very short term divorce proceeding you do have to prove to a court cruelty or adultery which means obtaining reasonable proof these things exist. If your partner is proven cruel or a cheater then really are they worth defending their custody so vehemently? Most no fault divorce state requirements require a mutual separation period well beyond the gestation period of pregnancy (one year is the most common) . Even if you timed a separation so that you got pregnant right at the beginning of starting the clock that baby would be three months old before you would be eligible to divorce.
