What does it mean that your boyfriend's Alipay avatar is still a big photo of him and his ex-girlfriend? They have broken up for three months.

See if he often uses AliPay. If he doesn't use Alipay often, he may forget it. If he had, he might have noticed, but he didn't feel anything, so he didn't bother to change. If you can't accept it psychologically, you can communicate with your boyfriend, express your thoughts and understand his thoughts, so as to solve the problem well. Don't be paranoid. It is recommended to communicate as soon as possible.
