I categorised my friends into three groups when I lost my mum.
Friends who could cope with me going through something tough and sticking it out - ie the one who let me sob my heart out in a cafe and all she did was keep going to get me more napkins for the tears and listened or the one who came with me to help us start clearing the house.
My sticking plaster friends who could cope in small doses but then suggested ways to make things better, move on.
And those who just really struggled to know how to help me and pretty much disappeared from my life for a while.
All are just as good friends - in fact I can think of a friend for each category and over the past 11 years we are still as close as we were before I lost my mum. Some from the first category who are now more distant than those in the second two.
One in the last group had lost her MIL, who she got on with, not long before and I think she struggled to support her husband, she is not an emotional talk about things kind of person. I like to talk so she probably felt out of comfort zone so effectively stayed away. It hurt but on reflection was probably for the best.
Now is really not a time to be 'ditching' friends - we are rubbish at dealing with death in this country and lots of people don't know what you need.
I agree with others if you need practical help be direct and ask, don't rely on her for emotional support because not everyone can manage it that well - not something to be judged for just a fact of life.
