You didn't offend me really. It's just one of those that infertile couples get sick of hearing. It's been a long time (10 years) since I was doing the infertility thing, so I've put it in its place in my life.
Now I hear "Why didn't you adopt?". Because DH & I had reservations about it that we could never resolve, so it didn't seem like the right thing to do
for us.
Now I hear "Why didn't you do egg donation, surrogacy, sperm donation? All of those felt,
to us, too much like pushing the hand of God.
Please note I make no judgements on other peoples' choices.
Plus, now all the people who got pregnant when DH & I were trying have teenagers, and I have to tell you, being childfree isn't so bad in comparison to raising teenagers.
