Name changed as she might be on here and I don't want this to be linked to my usual username.
Here's my AIBU, I am trying to be as short as possible.
I'm 29 and I decided to go back to uni for my second degree last year. I met a girl who's a bit older than me and has 5 children (relevant). I work full time (though quite flexible) while doing my degree so life is a bit hectic, I feel shattered pretty much all the time. I go to uni to most of the classes (this requires a lot of effort) and take relevant and very organised notes (on my laptop). Some of the classes don't even have course material so it's just the book and what the professor says in class.
So this woman, let's call her X became my friend last year, in the first year of uni. She seemed really nice and I always kept her a seat next to me (always front or second row as otherwise you can't hear anything!) as she was always late (she still is). She kept saying that she's really busy with the children (she doesn't work) and asked for some of my notes which I was happy to help with.
Problem is now she's always late, rolls in 15-20 minutes after the class started and she sits next to me in the front row. She asks pretty much everyday for notes and I've been too ashamed to say no so far.
I realised she's taking the piss last week when she's been in town to have lunch (while I was waiting at uni for class, didn't eat anything in that day), came in 45 mins later and asked for my notes
I don't want to help her anymore because I feel it's only me who is pulling the weight in this relationship and she's taking the piss. She doesn't even say thanks anymore!
AIBU? If I'm not being unreasonable how can I be assertive?
