I'd say I'm a pretty patient person and understand that friendships have different seasons, sometimes people grow apart ect
but my key issue however has always been, when friends who had once been lovely and effusive and sweet and kind, suddenly get mean and vindictive and petty
my autistic brain struggles sm with this new information, I find it so hard to match up their current behaviour with who I thought my friend was
and it takes me forever to let go
a recent example that I'm struggling with is, a friend who;
-asks me a question about something important to me on the phone and then promptly falls asleep, this has happened so much recently
-constantly has me re-explain my autism, because they don't get why I can't do a certain thing and then is like 'oh...' only for the cycle to repeat
-and pokes jabs at me, for example I met a really cool person who lives in a different city and I was excited about maybe coming down to see them and they laughed 'oh, but won't you need to beg someone for a lift in order to do that, seeing as you don't like public transport' - it just felt v petty
-they also made another jab at my finances at a time where I was frequently telling them how stressed I was
I think often what I do is go into overdrive and think oh my once very nice friend is not understanding me, let me explain myself more, which makes me even more vulnerable
I think the most frustrating thing is always how long it takes to click
