This thread is very relevant to me today as I have finally come to the conclusion that I've been slowly withdrawing from a friendship of 15 years.There will be no big dramatic showdown, tbh I feel instinctively this friend senses our friendship has run its course.But I feel sad nevertheless.In many ways she was a good friend when I went through a bad patch in the early years and I will always value that,but likewise she got a lot of support from myself and the whole family.Indeed I posted previously about how much hospitality she enjoyed in our home,she was a constantly sat in our kitchen.It was never reciprocated with invitations to her home,and tbh I accepted that until recently.I now know for a fact she's developed a hoarding habit. That's not the reason for wanting to distance myself,as I understand that's a mental health issues. But in recent years she's become very self involved,has what my DH calls 'victim mentality' and I now realise she has a habit of 'embellishing' details of experiences,and if there's anything I hate it's dishonesty.To be fair I think she has a lot of underlying issues.It sounds harsh,and if she wants an occasional catch up,and instigates it maybe I will meet for coffee.But some friendship start to drain energy,are negative rather than life enhancing and are best ended.Doesn't make it easy though.
It's only the second time I've felt a friendship becoming toxic.The previous time I realise now I was definitely being used,and like you OP when something happened that caused tension,and I then appologised even though I felt it was as much her fault I was cast aside very promptly.It's hard not to take things personally isn't it ?
