how to keep our relationship strong??so confused..

Hi..Im so confused right now :( I just want to read your advices..
Here is what's happening to us..we were really good 4-5 months ago but when she started following SNSD (Girls Generation) we are only spending 3-4 hours in a week! the worst thing is its even sunday! I kept on inviting her over to my place to have a dinner or lunch but she always refuse saying that she is shy to come. she spends all of her time sitting in front of her computer searching for new performances of SNSD. Do you think that her addiction towards the group is going overboard? I also know the feeling of becoming a fan of someone but not to the extent that ill spend my whole time with them ignoring the ones i love..pls help.. :(
