I think it must say I am being unreasonable but I do need a rant on here rather than to DH who I think is really surprised with MIL's behaviour.
MIL very kindly looked after the DC's this weekend at our house whilst we were away at a wedding. Often my parents help with childcare but MIL had previously indicated that she's really like to have them so when we got the invite through 6 months ago we asked her and she agreed to have them.
She was going to come to our house approx 2 hour drive from hers on the Friday, spend the day with us and then we could take her and DC's out to dinner on Friday and then we go on Saturday morning and come back on Sunday lunchtime. The plan was that she'd then stay with us until Monday when she could go home if she wanted or stay as long as was wanted.
However she actually came on Saturday morning as she said she was tired and wanted a rest before she came to us, this was ok as we just delayed our leaving time. Not a particular issue, we did miss the ceremony bit of the wedding but not a huge issue as we'd never confirmed times with her. But on our way home on Sunday DS called to say that MIL wanted to go home and were we close because she was on her way out the door!
MIL did leave without us being home, we were only about 20 mins away but it was 2pm on Sunday, not late and around the time we'd planned to be home. We called her and asked if she needed anything as we were close to home and said did she want to stay until we got back and she said no. 'What was the point'.
Somehow, I feel we're managed to upset or annoy her but I can't for the life of me think how. Either that or she's not feeling very well. I've sent her some flowers to say thank you for having the DC's over the weekend, so hopefully they will cheer her up. But it is all a little odd.
