<human>: My boyfriend and I have been together for about a year.  Prior to dating me, he was in a long term relationship that ended in a nasty way, resulting in him having major trust issues.  As with most couples, we have had some ups and downs, but nothing that communicating hasn't seem to work out.  Until now...

Lately, I've been having questions that can't be definitively answered by him (things pertaining to the time-line of our relationship).  Due to this, my thoughts have been spinning out of control.  I tried talking to him about it, and it helped very little.  I tried talking to friends and that didn't help much more.  So I installed the app Whisper to post things in the hopes that the immediate nature of posting things could help me settle my thoughts. (It is worth noting, that this is how he and I met, then we both uninstalled it shortly after seeing each other).

This weekend, he was putting music on my phone from the computer.  When he plugged my phone in, he saw a folder for Whisper.  He then, for a lack of better words, shut down.  He didn't tell me to leave or stay, so I stayed, but he was distant for the rest of the day.  He didn't touch me at all, which is not normal for us.  Sunday morning wasn't any better, and he told me that it all feels like a dream and that he's just numb even though he feels that he should be upset.

We talked, I told him everything that I had posted, I was even willing to show him my phone and have him go through it, but he refused.  But he's struggling to believe me even though I did nothing wrong.  I'm giving him space in the meantime, which isn't the easiest.

 
Is there anything else I can do to help make this situation easier?  How can we/I deal with this pre-existing trust issues in the future?

Can you give me a shortened version of the text?
