How should I tell my boyfriend he should pay for me?๐Ÿ˜‚๐Ÿค” Like we're in high school, we both play sports, we both really don't have time for jobs right now, and dating isn't cheap I get it... But we've been dating for about 3 months and I've been paying for everything when we go out like my food and stuff, not trying to be bitchy about it but he's never even offered to pay๐Ÿค Help๐Ÿ™†๐Ÿพโ€ผ๏ธโ€ผ๏ธ
