hammy do you still pay her some attention while youre watching football?? maybe its more attention she wants, not necessarily that she doesnt want football on the tv.
lummy watches football all day sunday (also NASCAR mixed in there) and I dont have any problem with it whatsoever. I go about my business while he watches, but he also pays a lot of attention to me (in general and also while he is watching football)
perhaps she feels shut out when youre watching football (i wouldnt be surprised if you were indeed shutting her out inadvertently) and all she wants is more attention throughout the weekend.
or maybe she's really really needy, in which case, she needs to chill and let you enjoy the sport.
