My mum was going to have my daughters yesterday while my partner and I went out for a meal that we'd booked, I asked her if she'd rather I asked my partners sister instead as she said her shoulder was hurting, she said she'd be fine. Then an hour before she was due to arrive she got her boyfriend to text me to say she wasn't well and wasn't coming (often says she's not well but then goes out for coffee), luckily my partners sister was still free and had them for me so no harm done.
Over the last few months she's been having my children once a week while I work for a couple of hours until my partner gets in from work. It's been quite stressful for me to get dinner prepared and served and then get my daughters in from school and rush out to work, so I rang last night to say I'd been thinking about it and for the new year I'd change my hours to start once my husband gets in. She said I'm a liar and it's obviously because she let me down yesterday, I'm not lying, I obviously timed it wrong in telling her that but I didn't think it through in that way.
Anyway she's now ignored me since, even though I've sent her various messages that she'd usually reply to. To put it into context she is so easily offended and has ignored me for weeks on end before, once because I asked her not to give my children sweets before dinner, so I'm not surprised, I'm just so bored of the emotional drama. Prepared to hear that I'm in the wrong!
