If your girlfriend always mentions her ex in front of you, it can make you feel uncomfortable or bothered. In this case, you can consider the following ways to deal with it:
Direct communication:Communicate openly with your girlfriend and express your feelings about her mention of your ex. But make sure to be calm and respectful when communicating.
Set Boundaries:It's appropriate to tell your girlfriend that you don't like to hear about her ex too much and want future exchanges to focus more on each other's current situation and future.
Shift the subject:When she mentions her ex, you can try to subtly shift the subject and steer the conversation in something other, more meaningful.
Understand her motivations:Sometimes people mention their ex because they are still dealing with past feelings and need some time to heal. Understanding her motivations may help you cope better with the situation.
Seeking common ground:Try to find topics or activities that interest you both so that you can focus more on things you like together.
Seek professional help:If the problem persists, you may want to consider seeking emotional counselling or professional help to deal with it.
Most importantly, establish open and honest communication, but also respect each other's feelings. Make sure to be rational and respectful when solving problems.
