Relationship problem: What would you do in this situation?

You know in your heart that it wasn't just the money. He is a just not realistic and he is certainly not considerate. If you weigh up the contribution you each made to the relationship it is not in any way equal. I don't think you are a fool to have had hopes and even to have loved him, but that is very different from taking care of him for ever. You are absolutely right to break up with him.
