Don't let race stand in your way. If you love him and he love you. You will find a way to work through it. And as far as different cultures. That's a plus! You will always be learning something new. And babies, if you two get married one day and have babies, they will be some of the most beautiful babies in the world!
So, Sandy, really think about it and if race is the only thing that is holding you back. Don't let it. You will regret it for the rest of your life if it is in fact love you are feeling for this man. I know this for a fact. Although what happened to me had nothing to do with race. I let something (something stupid and superficial) get in the way of the best relationship I ever had. The one time I was sure that I was really loved, no doubts at all. I left this person over it even though I loved him. He was hit by a car and killed just a few days later. Had I not let this stupid thing get in my way, he would have been with me that night instead of running out of gas and walking down a dark highway where he was killed. I regret it to this day.
I know it isn't the same as race but when I read your post, I thought about Gary. I just don't think anything should stand in the way of love, especially race.
