I think that both of you should be wise, and honest, and see everything for exactly what it is.
REALITIES TO DEAL WITH:
1. You love each other, and ethnicity is obviously not an issue between YOU TWO.
2. Some people ARE going to insert stress into your relationship, because THEY are racist.
Both of you need to be willing and prepared to deal with this.
3. Family problems can cause a lot of stress later.
Again, be sure you are both being honest and realistic, and that you're both willing to deal with this.
4. Although skin color isn't an issue between the two of you, "cultural" issues could still cause problems IF you are from different cultures. If you have cultural differences, be sure you're honest about it, and explore those differences.
Conclusion:
Just be honest with each other, realistic, and talk about these things openly with each other.
If you can discuss all these obstacles openly and honestly, and you're both prepared to take them on...
then the relationship is probably strong enough to go forward.
I'd also recommend you get some normal pre-marriage counseling at your church, if you have something like that available.
