He will have to communicate with his ex-girlfriend on occasion. Remember that your companion is also battling. It is difficult to start a new relationship with children. The most crucial component of your relationship is this. Don't be concerned if he feels love or sympathy for his ex. It's quite normal. He adores his children, and as the mother of those children, his ex will always have a special place in his heart for them. Your partner's life is already filled with complications. You don't want to be the source of further anxiety or stress in his life.
