Hi there!
I'm so sorry about what you are going through. I don't have much time now but if you have an iPhone, I know of an application that you can download and install on your computer (It costs about $40.) that will extract your texts with timestamps for you. It's quite useful for court. I don't know if it works with devices other than iPhones but let me know if you want to know more about it.
Thinking of you,
Doxie
Thank you! What's the app? Dose it time stamp photos too ?
