I am a woman who was 'tricked', my ex told me he was infertile. I'm not sure whether he genuinely believed this, or he just didn't want to put on a condom (my guess is the former) but I don't expect sympathy. If I was adament that there were to be no babies I would've gone on the pill. This was a very long-term relationship.
The dad has walked away and was back to spreading his legs. He controls his own body - he didn't have to go through the pregnancy...or the procedure to which you are referring. I have no control over his body, as he has none over mine. My fertility is mine, not anybody elses.
