It seems logical that people in a relationship should be equal partners in all areas. Sadly, that’s not always the case. In some relationships, for example, one person becomes the main breadwinner while the other relies on their money. If that’s agreed upon beforehand, it’s okay, but again, it’s not always the case. Sometimes, people tend to be pushed into these positions without agreeing to it. Just like today’s OP — they got tricked into paying all the bills in their relationship, and still, their girlfriend controlled even their smallest purchases while she wasn’t doing the same for herself.
