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.
Please try to spend time with them. They will understand. Give them some time.
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.
