it is always the option of one person to answer or reply to a text or call..but hey thanks for that heads up...sounds like they wanted to let you know that they still had some control in the relationship.

look friendships change. one person moves on, goes to school, finds new lovers, new friends etc. it is always a dynamic. a dance. people move in close, then separate, sometimes they come together again, sometimes not. you need to decide if this person's role is important to you. if she has a tendency to cut people off, and you know it, well then you might already know your answer. be patient.

I had a very close friend. we did everything together, spoke daily. when I decided to move from my home to a place 380 miles away and buy a place the dynamic shifted. she felt before she was a "caregiver" for me and by moving I was showing I no longer needed someone for that role. prior to the move she stopped talking to me and calling. 7 yrs later things are chilly. but I didn't need someone to hold my hand..i am strong enough to survive without being babysat.

perhaps your friends has the same such issues.
