Why don't you marry her bhatij. You may find a real love on her, besides a green card and a grown up son. Don't tell me you already have both ;)

i have a friend who is around 35. He married a latina, who must be 45 plus. The went to Nepal together. It seems they are planning to make a baby together. They look very happy with each other.

I know you are way younger than that 35 years guy, but it is always good to start a family if you find a good partner. Just a suggestion. And, if it is not a real love don't let a person double your age to screw you.
