I’m on Team jfnutffr. I think while the OP may not have reacted in the best possible way, it is a valid reaction when your parents tell you after the fact “oh, well, if you had chosen Chicago, we would have given you another $1000 over what we said we would”. I’m sorry but that’s quite the a$$hat move on the parents’ part and I’m not even sure I would have believed them. IF the parents really thought Chicago was the best place for their child professionally and personally, why didn’t they say that earlier when the three of them discussed it? That’s just setting the child up to feel inadequate or resentful.
Next time, don’t say this part. You can think it and truly believe it but keep this to yourself. Why? Not because they’re right but because it won’t help your relationship with your parents. As for being justifiably upset and being selfish - this isn’t mutually exclusive. You can be both. It’s understandable you don’t like being manipulated by your parents, using money as a weapon. But you also need to understand, it’s their money.
