Had this been a shidduch proposed to her parents, researched ad nauseum, and they said yes, it would be a big kashya. Usually when there is a disparity such as you describe, a big red flag would go up: “DID THEY AGREE TO ACCEPT ME WITH ALL MY DISADVANTAGES BECAUSET THEY HAVE A SKELETON OR THREE?”, in which case you might want to honestly ask the young lady what skeletons there might be, so you could make an intelligent decision whether to take them on. (I am saying this for those who might find themselves in such a situation).
OTOH, since it is a ‘boy’s market’, a disadvantage or disparity (or two) might be insignificant. But three?
However, in your case, none of this applies. Since there was no research, the girl liked you before hearing of your trials and tribulations, no such caveat. You just need to be sure that the parents appreciate & accept you with all your baggage, since the lack thereof can be a very big challenge in married life.
