oh hell. situationship/ roommate ?? good luck charlie. you need to just tell her straight up, hey its important to me right now to save money which is gonna mean i cant buy you as much as i wanted to. then maybe ask her (if like gift receiving is her love language) what are other ways she feels cared for by you, like what are other ways you could give her that kinda love without spending money. maybe you could make her things or write letters
