No I have not offered her food when I cooked or brought home cause I tried to talk to her a couple of times and she did not respond. So I am also not talking to her. I slept in a different room one night and that made absolutely no difference to her. So I started sleeping back in the master bed.
She has been cooking for herself and kids. She has ordered Pizza once or twice as well. She just has not bothered to talk to me or offer any food. When I took food home I fed my kids while I was eating.
I had come to know long after I was married that she pulled similar silent stretches with her own family too before she was married. She did not talk to her own parents for weeks.
Thanks everybody for suggestions and comments. I am not going to go file any separation papers… I will try to break the ice myself tonight or tomorrow.
