Three years ago my best friend since primary school (we're in our early 40s now) had a near death experience. Thankfully she recovered but since then her attitude has been very much living for the moment, putting herself first etc which I completely understand.
However this has mostly taken the form of leaving her DH to go off with her old boyfriend from secondary school. Unsurprisingly the new boyfriend hasn't really worked out (although it's not completely over either) and she is still mooning over him like a teenager despite him treating her quite badly.
She is also overlooking what the effect of all of the last 3 years including the near death experience, pandemic, parents' divorce, mum's new relationship etc is on her children and she is so wrapped up in her own life (and her on off relationship) she is basically emotionally neglecting them as well as making some really damaging choices that will come to haunt her later.
This is where my problem lies. I don't want to lose this friendship but I also don't know how to continue being friends with her when I feel so disapproving over what she's doing.
