is having a goal a dream that bad?

my bf’s sister accused me of being a *********. I am very offended with that statement, with the fact that i spend equal money with my bf for everything, I did told my boyfriend about my dream house, however the purpose is to encourage him from his current state, i want to see whether he is a really harworking person, he had no savings yet i love him, yet this sister of his tell stories to his family about me being a *********. somewhat i laughed so loud in my heart because she is actually the spoiled one, who is always asking for money from her brothers. such a shame.
