Been best friends with girl A and B since school. A and have been best friends since year 7. We’ve had moments in our lives where we haven’t seen loads of each other due to work relationships holidays etc but always tried to make time to meet up and called regularly. Throughout our late teens and early 20s we went out twice a week atleast together then it turned into dinners every other week or cocktails once a month I’m 28 now. Then lock down happened she also got engaged we spoke a lot but couldn’t meet during this time but during last summer we hung out and called loads discussed the wedding etc. friend B got a text saying what’s your address for the invite but never received one I then stop hearing from her. she’s started texting back but ghosting after a few texts and would answer my calls but always have to go or say she would call me later and never did. Recently I had a family member die and she messaged me about it and when I replied to say how upset I was by it being so unexpected she ghosted me.I’ve just found out that her hendo is coming up and she getting married in 78 days. I feel really hurt by this as I we where both so close her mum even still speaks to me over messenger to ask how I am. I just want to no what happened how can you just end a 17 year friendship.
