<human>: GF[F26] is a redditor, so I[M30] won't get into details, we've been in a relationship for 4 years. A few months ago my gf began seeing some clues(planted evidence? not sure what to call it) implicating that I cheated on her.  
  
For the record, I have never cheated, I've been cheated on myself and quite honestly up until this drama I've been perfectly happy with our relationship, both emotionally and physically. In fact I spent the time before this planning on proposing. Hell I even have the ring hidden away.    
  
Now I have some friends and even a company which was involved in how the evidence was planted, finding out who is doing this and how.  
   
But I don't know how to live in a relationship where I feel like she doesn't trust me. I'm staying positive, trying to do little things to show I care (which I do). I've backed off on our physical/sexual relationship. But I don't know if even proving my innocence will repair the damage or if she will ever even want to be intimate with me again.  
Right now I can tell we are going through the motions of being caring, but I feel so singled out.    
  
What can I do?
