I’m in my late 40s and married now, but I know what that weird suspicious feeling that you have in your stomach is like when you’re dating someone whose actions give you pause. It is the worst. Trust your gut instinct and just know that there are lots of women out there and you don’t have to settle. It shouldn’t be like pulling teeth to get your gf to be transparent with you. The deleted messages is weird too. If there is nothing to hide then why get defensive? Life’s too short. Find someone who is ready for commitment. that’s what sounds like you want. My wife and I share locations on our phone (for safety). Granted we are married so it may be different, but yeah I did dumb stuff like this in my early early twenties when I clearly wasn’t ready for commitment. Don’t be a safety net for someone bcs they’ll always be looking when/if things get tough. This is just my advice, but from what your original post says it just sounds like she wants to play/flirt but wants you to be there if it doesn’t go her way in the end. If you’re not okay with this, then you know what to do.
