What do I do

Taylor

My boyfriend and I recently got into a fight Saturday because he thought I was doing something behind his back on my phone when I was really just on Pinterest. We talked it over and then today we had lunch together and he says “I need reassurance that I can continue to trust you and I need reassurance that you weren’t doing anything” what do I do? He says he trusts me but obviously he doesn’t if he had to even ask that question
