Well what he remember of anupama when she has not given him anything even their bedroom also she used to talk about Shah's. I guess he told it was my reality which turned into dream , so basically he was thinking of his past life
From where u got Anuj only wanted anupama for himself? Don't care 4 aadhya , be it fight before leap , or begging in front of anupama to return in their life in his imagination or informing adhya about meet with anupama every where he considered adhya , himself as one unit , he asked why can't she be completely their , why should they adjust , return please as we can't love without you, now we will live in real terms as we were name sake living , he would have happily meeting anupama if he don't care for aadhya
Romantically thinking for his own wife is creep in those 3 yrs , God know what we call vanraj
