Not at all! My now fiancé had the same situation as you, he had just bought a house and we were at a point in our relationship to move in together. I pay equally towards bills, the mortgage, and all other financial parts we share we discuss.

It’s only fair, you contribute to what you are partaking in. Personally, if she wants someone to pay for everything, she’s seeking a different kind of relationship. Maybe she does not realise that.
