Jomarie I'm sorry, I read that wrong, I thought it was an invitation!
And no, I would have said the same at 11 am.
I know Tegan I'm the same, always with hindsight. But I have had my moments of saying the right thing at the right time.
For your MIL to keep embarrassing you in front of others is not on, that is why I said to say something she would be embarrassed back by, maybe not as bad as I said but she needs to know what it feels like. Or have a quiet word but I wouldn't say it was her son's doing, I would just say that as a couple you have decided to have some time first before starting a family. Put it that he is such a wonderful man, you want him all to yourself for a bit first.
