I cant take this anymore ughhh help !?

i have this friend i knew her for about six years now we were close throughout middle school except for 8th and 9th grade we kinda distanted in 10th grade we had a cl together so we came closer then we were before the first semester everything was good like i never wanted to lose her we use to talk everyday tell each other mostly everything. Now things have gotten so weird like well ignore each other at school then we well talk like nothing ever happen. Were out of school right now so we text everyday but shes so boring to text she doesn't write no more then five words. shes the one who texts me everyday so i don't understand why she texts me just to be boring. I guess shes the type of person that doesn't like to talk out anything because we have so many problems i feel as she ignores them not me. i feel so over whelmed because i don't even want to be bestfriends anymore this **** takes a toll on me because we've been friends for awhile shes like my favorite friend and we talk everyday but im just not happy anymore its not the same and since shes not the type of person to talk about it hard because i just hold it in and i just build up anger ! what would you do in this situation because i don't want break this off and regret it nor do i want to stay mad. should i tell her shes boring to text? i cant just tell her this because she wont give me the answer im looking for give me your opion!
