Does your boy still think of the former? What attitude you should have to conquer it
Do you feel that your current boyfriend has not yet forgotten the former and has a state of restlessness and jealousy? Your first impulse is to make a scene of nerves, but this is not the solution if you want to prove that you are the woman she needs.
Try to put yourself in his stead for a while. If he loved the former very much, it would not be so easy to pass all over at once. Surely it has happened to you to think of other partners. After all, there is a difference between thinking of the former love and still being in love with it. And you will have to figure out in which category he falls. If his feelings are not strong, you will succeed in conquering him and becoming the only woman he thinks about. Instead, if he expects any opportunity to be with her again, you will suffer.
Keep your calm and try to have a positive attitude towards the whole situation. Give him time to forget and show him that he is much better with you, so you will never want to return to a relationship that did not make him feel fulfilled. If she even shows signs of wanting to get closer to him and exceeds the measure, maybe you should show him what his place is now.
The memory of your ex-girlfriend can break the bond between you if you do not adopt the right attitude. Instead of making jealousy scenes and talking to her about it, you better pay him more attention.
