Re: Should I worry?
I know when I'm upset, I will go quiet and not talk, which is the most ineffective way of handling things. She might not be great with communication. I know with my boyfriend, when I ask him if he is alright he will either say yes or no and actually mean the answer. However, when I'm upset I will always say I'm fine. Eventually I will come around and admit that I am upset, but everyone is different.
I would try talking to her, bring up the fact that you feel she's been distant and ask if there is anything you can do.
Communication is really important in a relationship. I understand that this can be easier said than done though.
