My partner thinks that I've been having an affair or thinks I might. I have not and will not but her anxiety doesn't let it go. She rationally knows it's not happening but that's not how anxiety works. I have tried different strategies to help her quell her anxiety about this. 
Such as: 
-Adding her to find my friends so she always knows what I am
-Leaving my devices unlocked around her When I leave the room
-leaving my email logged in on her phone


Should I add one of those spy softwares to my phone so that she can always see what's happening?

I worry that she is too embarrassed to do any investigation because she thinks it's silly but I would like to take down as many barriers as possible to put her mind at ease without making her feel crazy.
