Yeah that is a shitty situation to be in, to say the VERY least. In the end I think abortion/no abortion is her choice as its her body, but as you seem to be faithful to her and have chosen the right choice instead of the easy one (something very few guys seem to do), I'd hope she'd at least talk it over with you.

Also, adoption is trickier than people think. All adoption agencies in Canada have a 7 year waiting list and in the USA I believe its worse.

Whatever decision she and you come to, I wish both of you nothing but the best.
