My wife is of the same opinion as me.
firstly im glad your wife is in agreement. but you worded it as if it was purely your choice.
its her choice to which you have to agree(stay with her) or disagree(get a divorce). she still has the control
its you that has to agree or disagree to HER decision
But then, when do you define the cut-off limit where it is still "fine" to terminate a life due to X, Y or Z reason? Is it before they "become of age" ?
there is no one rule for everything
life and awareness are 2 different things
take a 40yo person who is getting dementia. they become no longer aware and no longer capable of looking after themselves. so its not a case of not putting someone in as their carer/guardian because they passed some age limit of awareness
take a terminal cancer patient who is fully aware of his actions and wants to die. he should be allowed to, and not be forced to be put on life saving treatment
take a terminal cancer patient who is in a coma and unaware of his actions. should be kept on life support for 1000 years? instead someone who has care/guardian status of someone unable to make independant decisions has the power to make independant decisions
so for pregnancy, the MOTHERS has the power
obviously the decision should be on the best interests of the child, but also how it will affect the womens future
so when we know that at say 25 weeks a fetus wont survive if birthed or surgically removed(c-section) the fetus's best interest is not to be punished with 1000 years of life support because it doesnt even have developed lungs of its own
and wont have the brain capacity to learn and live an active independant life
however if a fetus gets to be the stage where science knows it has a good chance of a good active independant life. then it should be much harder to warrant an abortion. unless its proven that the child would negatively impact the mother beyond reasonable amount
it also impacts the debate of 'loss of life: murder or self defense'
loss of life is just loss of life but the reasons for it need to be defined
just calling all death murder is ignorant
death happens. its the why that counts and who gets to decide that counts
so if a mother knows for sure that the baby is going to cause more harm than benefit to the mothers life and negatively impact her life more than she can expect to cope with. then its self defense
