A little hurt and confused 😕😢

So I have had this woman named Kim on here who Iv became friends with we even added each other on Facebook and talked everyday.. Well we were both TTC at the time I got pregnant in late November and told her about it she seemed fairly excited this was during the time she was testing she has been trying for 8 years and I was sensitive to her situation I never bragged it anything so one day she tested and I swear I seen a faint line on one of em she said she was gonna retest and let me know in the morning on Facebook so I get up and go to message her she had me blocked on fb and even on here with no explanation or anything and to this day it hurts my feelings. Why would she block me out of no where like that? 😕😢😩
