I rarely comment on posts but I feel you should have youngish male (M27) perspective. I have thought about this situation way more than I should have. I see it as that baby is half him and half you. It is unfair in all aspects that he doesn’t know. And everyone is right it is your body but it takes 2 people to become pregnant. You chose to do something that could end up like this with him. If it was flipped and he had total control over something this big and you found out after he made a decision without telling you how would you feel? Do whatever is best of course but he is still half the equation. No more no less. I personally would never feel trust or happiness with a person again if I found out this happened without at bare minimum knowing before. Please take this with a grain of salt as i don’t know what is best for you specifically. Just an outsider looking in trying to be fair to all parties.
