I email my Ex about issues related to the children as that way I have a copy of what has been discussed and can remind him what has been agreed. I sent him an email on Monday asking about plans for Christmas. He hasn't acknowledged nor replied to the email. How long is reasonable to expect someone to at least acknowledge or reply to a personal email? His messages go straight to his phone so he would know as soon as it was received (he isn't the sort of person that would go days without checking his email, he would read it as soon as he receievd it).
And for those of you that don't understand why I am trying to discuss Christmas arrangements with him now, it usually takes quite a long time to get confirmation from him one way or another about things and I need to organise childcare aroudn work arrangements and that takes time as well. Although the subject matter isn't important but rather how long would you expect a reply to take?
