patrick, thats a normal teenage attitude, but at 19, to be honest, i wouldnt have thought youve faced much that life has to offer...
shes a bit older than you, meaning , maybe she was waiting to have kids when she was married and settled, maybe you not working and being younger is different to what she has been imagining for the last 20 years of her life,
if i was you, id take this one for the team, and let her do as she wishes, maybe if you are together in a few years and more settled in life you might plan for children, but at the moment it doesnt sound to me like you should dwell on this too much, it was an accident, and maybe it would be for the best to keep the peace,
and women turn into nasty evil hellish biengs when they are pregnant, and everyhitng goes saggy and wrinkly too... (only joking BTW)
