Hates when I grab his phone 🤦‍♀️

My boyfriend and I have not been on good terms lately but he says he’s trying. Today I tried grabbing his phone 📱 he literally got up quickly and get in front of me he was angry 😤 I’ve never seen this reaction throughout my 3 years of relationship with this guy. So I was like what don’t you want me to see he says “ nothing I just want my phone back” he says he doesn’t want to give it to me because I am gonna delete pictures that I don’t look good in. He always uses that excuse. He was really bothered that I wanted to get his phone. What do you guys think? Do you think in a healthy relationship we should be able to have access to each others phones?
