hot and cold

like i am so hurt right now like i dont get some people like my friend like shes being so hot and cold all the time and its like the same pattern, like all the time, and its really getting to me. im so hurting right now and i dont know what to do. and im to of a chicken to talk to her about it so cuz of that it just keeps going on like this. like she never used to be like this like before i met my husband she was never like this she was my 100 percent bestfriend and always had time for me and now she is acting like this. like why do things have to change for her with me? just cuz im married now? like why does me being married and her being single have to be such a big deal to make a friendship different? why????  i just dont get it!  feeling so hurt!
