LJDHC05, 3 years is a LONG time. I agree with thirdunity -- if you've been with her for 3 years and you're still scared to commit, you might just think about why. I know I would never wait for 3 years for a guy to figure out if he wants me or not. Of course, the correlate is whether she's ready to commit.
Regarding adoption: the self-righteousness of people who do international adoptions has been brought up (and I've actually seen it, too), but I also think that those posters here who said something to the effect of "I just don't understand why people don't adopt; we're going to!" are being somewhat self-righteous. There are MANY reasons why people do not or cannot adopt; guju posted some good ones, but there are many, many more. If people do not feel capable of adopting, it would be wrong to push them to do so.
I myself am unsure whether I could do it or not. My husband and I have discussed whether we would if the situation arose. I think my husband is more comfortable with the idea than I am. Maybe this is a flaw, but I'm not the type of person who would just adopt for no particular reason, or just in addition to giving birth to children. I've often thought that after my biological children grow up I might like to adopt one or two disabled children, but even that impulse has fallen by the wayside as life has caught up with me, and I realize all the other things I want to do. Perhaps I am selfish. Or perhaps I'm simply not cut out for adoption.
Regarding interracial adoption: a family we know, the parents both white, adopted a little girl who is black. They are also foster parents to another child who they hope to adopt, also black. The other important detail to this story is that this couple lives in an Orthodox Jewish community in the northeast. They are wonderful people, very unusual, kindhearted, and if anybody could pull this off it's them. But it's not going to be easy. I was at a party with them once and I overheard some girls talking, saying "why didn't they just adopt a white child? that kid is going to have a really hard time growing up."
I'm pretty sure that many of the national (US) black groups are opposed to interracial adoption. I can see why. It's difficult for a child to grow up looking different from her parents, and definitely if she will look different than the vast majority of people around her. I reserve judgement on the issue, though, because who am I to say what can and can't work? I suspect our friends will make it work out fine. In a way it may even be easier in the community where they live, because the children will probably not try to fit in with their black peers (they won't have any) by adopting much of black culture, while at the same time becoming ashamed of their parents. I had an aquaintance in high school who's father was black and mother was white; he considered himself black, hung out mostly with the black kids, etc., and he was completely humiliated if anybody saw his white mother. I felt really bad for him, because he was trying so hard to fit in. Unfortunately society is still racially divided, particularly socially. And it might be changing, but it's changing slowly. So the situation is difficult.
