I (21F) am dating a (21M) i have no belief he is the type to cheat, but I've been cheated on betore in past relationships so i always have that insecurity that he eventually will too. I also know the 'signs' of someone lying, manulipulating etc.. and to top it off i have manic anxiety and BPD. ..
So fast forward to 30 minutes ago i ask to borrow his phone to look up something on gps/maps (my service sucks and takes forever to load.) Well just so happened there was a recent unknown address that had been typed into maps a few days ago. I asked him calmly what the address was and his response was almost sarcastic as if he was supposed to know how it got there/had no clue where or who's address it was. But he had to have typed it in it, because it was in past trips. I told him ok fine if thats what you say yhen it must be that. But of course my mind is picking at it like a scab and i cant stop having the paranoia that he's lying. I don't want to blow it out of proportion if it isnt anything at all but my gut feeling tells me its not possible to have a random adress saved in past trips and for him to not know who or where it came from. 
So im asking for advice to help occupy my mind so i dont work myself up in a fit, and also advice on what you think is really happening. Should i trust that he genuinely doesnt onow or do i stick to my hapf traumatic twisted gut feeling.
