Last week my messages were taking forever to go through to my husband (we both have iphones and have imessaging turned on). So...I opted to send the message as a text message. This happened for another group of messages I was sending to a different person. Now, I can't get any of my messages to my husband to be sent as imessages. I've turned the imessage feature off then on, I've re-booted my phone; I checked his phone; I re-entered my Apple ID...NOTHING WORKS! However, when I try to send messages to a different person with an iphone, it works and sends the message as an imessage.
