I once had a friend like this.
My husband had a job opportunity in a town 2 hours from where we lived. I was on mat leave so we moved there for just over a year.
I had a young child and didnt know anybody, so I joined some baby classes and met a nice group of mums, we would meet a couple of times a week, but I still had the rest of the week to fill.
A lovely woman lived a few doors down from me with her son who was 4 at the time and not yet at school, she worked very part-time.
She was very friendly, outgoing, life and soul. She befriended me and was always offering ways she could help out, included me in local events, introduced me to other people.
It was all very kind and helpful.
Until the flakiness started to show.
I began to realise that she saw me as a bit of a charity case (despite my having my group of new mum friends) and that I was always just a charitable "add on" to anything she had going on.
I suspect a bit of ADHD with her as she would make plans, then I'd receive loads of rambling voicemails about how she couldn't do what she'd planned because x, y, z had come up.
She'd ramble through loads of possible solutions (none of them possible) leaving me as the one who would have to say "it's ok, just leave it".
She would then say something like "I'd drop you in a cake / souvenir on my way home!" and big it up like this was just as good.
Her heart was in the right place, but she definitely didn't see us as equals.
