Hey! Abortion is a womans choice as its her body. But a child is God given in my eyes and if that child was to be born with an illness then that was his will. Also, if theres that high of a chance, talk to her. Discuss maybe adoption or open up more on IVF and discuss risks of abortion. Also, maybe if you guys dont want children in the future idk how young you are. Legally, you can have an abortion before 6 months but the way this has been worded seems careless and you cant really have an abortion when you feel like it. It strains the nhs on where to put boundaries and this is a typical slippery slope argument. Maybe, use good contraceptive methods that reduces chance of baby but if you want a baby that bad. My advice is to speak to a doctor to guide you. Abortion in this case would be frowned upon because if you know theres a high chance of a peoblem, then its not the best idea. Talk between yourselves and seek help from professionals. IVF is the best shot but maybe try convincing ur spouse. Wishing you luck!
