It's understandable that hearing your boyfriend is receiving money from his ex could trigger feelings of concern and doubt. It's important to communicate openly and honestly with your boyfriend about your feelings and address any insecurities you may have.

You may want to have a calm and honest conversation with your boyfriend to understand the nature of his relationship with his ex. Ask him about the financial support she provides and the boundaries in their current relationship.

It's possible that his ex is simply helping out as a friend without any romantic intentions. However, if you feel uncomfortable with the situation, express your concerns and establish clear boundaries with your boyfriend moving forward. Trust and communication are key in any relationship, so make sure to address any doubts or uncertainties you have in order to maintain a healthy and trusting connection with your partner.
