Who pays in your relationship?

This is a big question for me and I just wanna know your ideas. I usually pay my share (tickets, food, anything) unless by bf insists or like when it’s a date night, but when we’re just randomly stopping somewhere to eat or sth I pay my share. I just feel like it’s the right thing to do and he’s not my bank account. But all of my friends think I’m stupid and that guys leave you more easily if they haven’t spent money on you. They tell me men should always pay and I spoil my boyfriend. This is important to me because I’m starting a new relationship and I wanna do what’s right. Tho I can’t even ask a guy to pay I feel like it’s rude.

Please tell me how you work this out especially at the beginning of a relationship. Thank you💕
