My mother is recently widowed (I posted about this a few weeks ago) and living abroad. She's early 70's, the death of her husband was quite sudden and unexpected. She came to stay with us for 2 weeks after the funeral having rung up the day after in hysterics saying she couldn't cope. I've barely seen her for the 10+ years she's been living abroad. TBH it had made my life a lot better. The 2 weeks she was here she spent sitting on the sofa expecting to be waited on hand and foot and entertained. She never said thank you for any of it. If it was the grief I could have coped, but it wasn't. It's just her. My health isn't great anyway and the stress of it made me ill. My kids barely know her and didn't like having her in the house (son had to sleep on the floor in the office so she could have his bed as we don't have a spare room, 3 of us work from home) and I don't know how my husband managed not to lose his temper with her.
She went home earlier this week and has managed a total of 3 days before messaging me and hinting that she's thinking of coming back. I had predicted this would happen so it wasn't a complete surprise, but I can't do it. She can't effectively move in here and sit around expecting to be waited on. She's already said a few things about moving back to the UK permanently, which we said we'd support from a practical POV, though we live in a very expensive part of the country which she can't really afford. I don't want to cause her any distress, but she already leaned on me far too much in childhood (my father was awful) and I can't parent her through this stage of life as well. I don't even like her that much. I messaged her back saying things would be difficult for a bit wherever she is, and had she thought any more about what she was going to do long term, but I didn't say anything about her coming back and staying with us. She hasn't replied. I know I have to set boundaries otherwise she'll move in and never leave.
But I feel so bad. The childhood training is hard to shake off.
