@Viswamitra Sir thanks for making me understand and you r giving me hope that my son will definitely change. Regarding counselling part my husband is reluctant he is worried my child may go to depression if my son thinks otherwise because of teenage. My husband also facing the wrath sometime but he is unable to be quick in decision as my son's class teacher also suggesting to observe and wait fir 2 more months. And I forgot to share 1 important thing with you all after the birthday card incident though it hurted me deeply didn't show any consequences to him and never informed my husband and left it like that. But yesterday when we r planning to go out I as its my DH birthday told my son its OK if you don't want to come it up to you you can watch TV and will bring lunch when we will be back to home. To my surprise he just joined us and didn't make any fuss. My husband is happy about it and thinking the step we took is working as he doesn't know card thing. I'm not sure it maybe or may not be. Knowing my son's nature I cannot trust him completely but felt refreshing after so many days. We continue to watch how it work. If its back to square one will definitely seek help. Thank you once again.
