I've been in a relationship with a woman for 4 years and we've done pretty well so far and have moved in together. However, on the topic of having children it's always contentious.

We've talked about marriage and she always brings up how she wants children. I'm not so excited about it but if I did, I would rather adopt if we did have kids, but to be honest I'd rather have none at all. 

For me, I don't want to give them any of the genes I have that gave me horrible anxiety since I was really young that really interfered with my daily life. Plus, I think the world is regressing with irreversible climate change and as resources and geographies change in the next 40-50 years, I can't say the quality of life would be something I would be looking forward to.

GF will not budge. She wants "her own" kids and to me that's really selfish. I understand why - since it's your biologic compulsion to reproduce - but logic can override impulse and I'd rather have none at all or adopt.

It's driving a serious wedge, but I honestly think I'm in the right.
