I'm sorry you did not receive a response to your post. By the time I saw it, it was a day old and I thought you needed an immediate response. If you still want to send him random text messages to cheer him up, you could try sending him a joke. What is his favorite kind of joke, a guy walks into a bar, sex jokes... For example, if he likes blonde jokes you could send him this one, my favorite 'How do you kill a bonde joke': Put a scratch and sniff at the bottom of the pool. ba- dump- pum! You can find jokes all over the Internet.
I'm sure he will appreciate the gesture.

sorry I just saw this post--

I send my husband texts that say -ummmm-thinking of you and he knows I am really rally really thinking of him..lol I always get a smiley face back..

A long time ago we saw a silly sci fi movie where it was about cave men and women--the main male and female charactre would always say (zug zug) meaning time for sex..I use this one often and my hubby knows..Just tell him when you say (----) whatever in betweenthe lines that you are really thinking impure thoguhts..He'll smile alright...:^)
