Financial red flags in a relationship are indicators that there might be underlying issues with money management between partners. One of the most common red flags is where there is a money imbalance in a relationship. This happens when there's a significant disparity in earnings or financial contributions, and it's not handled well. It can create tension if one person feels burdened or if the other feels disempowered. Other red flags include hiding purchases or debts, an unwillingness to discuss finances openly, having vastly different financial goals, and irresponsible spending habits. It's crucial to address these red flags early on to ensure a healthy and transparent financial dynamic in the relationship.
