pls help

my boyfriend accused me of cheating and wants to go through my phone or he wants me to send him my location to prove my innocence. my ex’s were very controlling, wanting my passwords and location, so in my new relationship i put up a boundary to not share all of that information. my bf won’t let it go though. he wants to go though my stuff and have my location or he wants to break up. we’re at a mexican stand-off right now, neither one of us is giving in. i love him a lot i would just appreciate some trust from him. it doesn’t make me feel good that he doesn’t trust me. my question is should i just let him leave me or should i let him go though my phone and break the boundary i put up?
