Sometimes we can get wrapped up in thinking that because we have given up so much for our children that somehow they owe us something in return. This is completely false thinking. We can have high and fair expectations of them and teach and help them to live a good life and make good choices, but our children owe us nothing per se for whatever we have sacrificed for them. The very fact that we are their parent means that we are going to be the one making all of the sacrifices, even if that includes our very life. We give of ourselves (and our happiness and comfort when necessary) to the extent that we can so that our children might live (and live well) to the extent that that is possible. That is how it works. Not the other way around.
