I dated this girl and it was so bad

So I dated this girl in New York and at first things where going really well then just her life started falling apart and I had to take care of her financially which I didn’t mind at first but then I started to feel like a sugar mama and then things where good for a little she was taking care of me so it felt equal then shit went downhill again . then here I am being a sugar mama again which I didn’t even have that much money ! . There was so many red flags I should have ran away from it . I guess we live and learn tho honestly I’m doing so much better without her I feel like she was only there for affection and attention from her . I think I need to set my standards higher
