I got married to this man with 2 beautiful teenage daughters. I absolutely love both of them and treat them as my own. I wish they knew this. They still find faults in me and feel that I have some motive behind marrying their father. I don’t know how can I make them believe me. I truly love them.
Try to talk to them, spend as much time as you can with them. Make them realise that they are your number 1 priority. They will understand, gradually.
Please try to spend time with them. They will understand. Give them some time.
