I have had this friend for nearly 2 years now and at first she was just part of a group where we met once a week. About a year ago we became more like best friends and at first it was lovely, wine nights, nights out, days out, meals out etc but then things changed. I can't exactly put fingers on when but here goes.
Her dh works long shifts and he earns enough to support them both but she insited she needed to get a job to get money (he won't share his, it's a weird set up) so before she got this job she mentioned that she would need me to babysit for 2-3 hours 3 evenings a week or whenever her other sitter wasn't available. Tbf i did say i would and she has been a good friend to me.
Anyway those 3 days turned into 4, then 5 & in the end it became a struggle & her dd became very bad behaved and started throwing things, not sharing with my dc and emptying all the toyboxes in my home. I said that i can't do wednesdays anymore and she was fine with this but in the end even 3 days was enough for me and i have slowly made my excuses but now she has another job and is starting to pile pressure upon me again, droning on and on about how she works (im a sahm) and how i only have to do Monday's.
Also in the last 5 months or so whilst i have a lot of my own crap going on she never asks how i am, it's always to ring up to see if i can babysit. She has started to show me up in front friends, blatantly taking the piss out of me but doing it in a giggly way. She has also made digs infront of friends i only babysit one day a week and how life is so hard for her
(she does 12 hours a week)
Then theres the meals where she forgets her purse or drones on about having no money and i end up paying. She then promises to pay for a future meal etc but never does.
All she talks about these days is herself and when she got some cash of her dh a few weeks ago (a rarity) she bragged about it to the whole group and not once thought to buy me a cuppa or lunch just bragging about how she was going to get new clothes. On this particular day she made a complete spectacle of me, but i laughed it off not wanting to go down to her level.
In recent weeks she has rang me around 3 times all about, will i babysit, and now ive got to the point i think i'm going to not answer the phone or be in on Monday (tonight)when she turns up with her dd because i'm fed up with being taken for a complete mug and i believe it's her turn to feel like me.
I have 4dc off my own, one with special needs and having her dd on top of this is a struggle. She is also talking about having another dc and expecting me to babysit for that one too in the future (which ive said no to by the way). But all i get it is "it will only be a couple of hours" 
Then one evening she also rang me to try and land him on me the following day and when i said a straight no, sorry i'm busy etc she retaliated with telling me in no uncertain terms that she knows i'll be home so why can't i do it. She just kept on haranging me. She also booked overtime this saturday before even asking me expecting me to have him for 2 hours that evening, ringing me at 9pm saying she as overtime and she knows i'm home. I got peeved and said no i cannot do it and made some crap up about not being in, she then went into a 10 minute chat about how is going to struggle to find someone & asked me what i'm doing this evening inwhich i said lying on the sofa, her response was that i'm a lady of leisure and was laughing to her partner in the background😡
I'm a single parent (sahm) of whom has recently got out of a rocky relationship that ended in violence & i may be losing my home soon and i just don't need this anymore. I don't want to lose the group of friends we are part off and i'm not sure of how to phase this friend out. Aibu to want this friend out of my life?? And any tips on how to phase out and put a stop to this tia x
