Two Aquarian females just need to know what to do

Please can anyone shed some light on this as just at my wits end.

I am an Aquarius with a loverly Taurus partner and my sister is also an Aquarius and would you believe it, her partner is a Taurus and totally devoted to her.

A couple of weeks ago and out of the blue, her Taurus partner was away as he was working as per usual and she also had to go out. This meant that she wasn't able to talk to him on the phone that evening (but she did send him an e-mail to say something had come up) which they have done religously every day when they are away. This was on the friday night. On the saturday morning, her Taurus partner's two friends were in a serious accident and are still critically ill.

He hasn't contacted her since but we know he is ok. Being both Aquarians and very humanitarian, neither of us can understand what is going on here?? Is it because she didn't talk to him that evening or becasue of the accident? I know most people are going to say its the accident, but there is a side of taurus males that we just don't get i.e always being there for them.

Neither myself or my Aquarius sister can think this one out so she can see what she can do to make amends. Please, any input to get this sorted will be most gratefully received. Many thanks in advance.

i think i get what you are talking about-- i know some taureans that can act quite childish if they don't get their way... i've been told the same about me occasionally :-P he'll get over it eventually, i'm sure the accident did play a certain role in his unusual withdrawl also (unforeseen stressful circumstances, he's probably racking his brain trying to assess the situation).. maybe a niec letter or card saying she misses him and is worried might smooth things over a bit quicker and show some needed support
