Apologies... This may be long as probably need to set scene so as not to drip feed.
Friend and have known each other since school, fairly close until university (days before mobiles were an everyone thing) when her course took her abroad. We lost touch and then recently reestablished contact after bumping into each other at her place of work.
As I recall her relationship with her parents was always strained, in her opinion they always favoured her older sibling. I don't recall ever meeting them more than once or twice so I couldn't judge if she was being melodramatic or not.
We are now adults approaching our 40's. I have had a couple of ltr's, married and divorced, am now a single parent although in a long distance relationship. She has never really had a partner, has all the free time in the world, does volunteering work with a big organisation (I do a lot of volunteering with a different organisation) and it is pretty much her only topic of conversation.
So... I have recently been able to buy my own house due to a very generous gift from my dad (he did similar years ago for my sibling) I am eternally grateful! I live in an area where house prices are low in comparison to most of the UK so was able to buy a large 3 bed terrace for dd and I. I love it! After some very unstable years it is the anchor I needed and has been a game changer for my mental health and my dd.
There is just the 2 of us at home, boyfriend visits most weekends, sometimes in the week depending on his work schedule. So I have a 'spare' bedroom. It is currently a bit of a junk room, we only moved in a few weeks ago so it's full of boxes in haven't sorted yet, stuff that needs to be put in the attic when I brave opening the hatch.
Friend is having a rough time, she lives with her parents, has done for the last 15+ years, they don't get on. From the stories she regails me with I have a huge degree of sympathy for her parents. At 40 she is still acting like a stroppy 16 year old, rebellious and down right rude and disrespectful. I haven't said this to her though. Her mum has basically told her she needs to leave sooner rather than later.
She can't afford to rent as only works part time on a low wage. She wants to try for a mortgage, good on her if she gets it it is cheaper than renting but honestly knowing her salary I think it is unlikely that with no savings she will get enough to buy what she wants. However, I have given her the details of my mortgage advisor and helped her look at what could be in her budget.
So... My aibu boils down to this... Friend came to visit the other day, having realised I have 3 bedrooms and 1 not in use she has decided that it is now her room and is going on about me sorting it out whilst I am off work (have half term off with dd) so she can move in.
I thought she was joking and just laughed a bit. She apparently wasn't joking and is now asking how much her rent would be, share of bills etc. I have said it would be zero because I'm sorry you aren't moving in, dd and I enjoy having the house to ourselves, I don't want a lodger. I have a busy job, Ed has complex health issues and I really hated house sharing at uni and have no desire to ever do it again! It is the fastest way to kill a friendship. She is calling me a cow and whinging that I am being unfair, her life at home is shit and she is being made homeless by her mum etc and basically laying on the guilt trip.
Aibu in saying no? The stories she tells me about her parents fill me with horror. If she is genuinely behaving in the way she makes out I don't blame her mum for throwing her out. I don't want or need the stress.
