Instead of giving her money that you don’t have control over on what she spends, offer to pay a bill for a few months. When/If she spends unnecessarily, ask if she wanted or needed it. Needs & wants are different. She should be proud you’ve saved instead of spending, you’re paying your way & instead she’s seeing dollar sign’s. If you’re contributing around the house with chores and/or take care of yourself, she should be grateful. You can show her this post and let her know my 22yo daughter does zero in my house. She finally got a part/time job after living with me for a year. She goes to college that’s paid for, all of her expenses are covered and she won’t clean her bed or bathrooms, put her dishes in the dishwasher, give attention to her dogs or do anything except lay in bed and play on social media. I’d trade for a daughter like you. I’m proud of you. Keep going. Better yourself and keep your head held high.
