What kind of mother are you??? Dev has proved himself time & again as a good son and brother. Worked hard day and night to be at this position professionally. Now what more do you want from him???
First time in his life, he has found love. A partner whom he wants to share his life and rather being happy about it, you are behaving like a other woman in your man's life. Grow up woman!! He is your son and not your husband.
