How do u react to not being allowed to touch ur bf’s phone? 19M 20F

Hi! I (20F) have been dating my bf (19M) for a little over 3 years. We live together and when we first started our relationship it was a common joke amongst friends how I was the only one allowed on his phone. For background anytime any of his friends except me attempted to use/hold his phone he immediately would snatch it back. When we first started dating he would even let me part time use his phone for 4 months due to mine being broken and no money for a replacement. Now flash to when we moved in together 1 year ago. We moved for college and no longer have friends rly (all moved across country) so we are attempting to make new ones and he is VERY protective of his phone. I’m not even talking about like just carrying it with him everywhere.

I’m talking won’t even let me put my hands on it while he’s showing me something, can’t use Google, can’t watch YouTube, would rather attempt to drive a type than let me put an address into maps, sleeps with it under him so that he will wake up if I even use it as a flashlight, and when I do attempt to use it to see he immediately takes it. Like won’t even let me text my own gma on the phone, he has to set it up for me and watches me the whole time.

I have told him that I don’t mind that he wouldn’t want me to like go through it, cause i understand like private messages and stuff; especially since he has just made a couple friends and prob has talks with them that he wants private. But told him that the extremity concerns me since it is a new and extreme (compared to how we normally are) behavior.

For comparison we both have each other’s passwords and he has gone through my search history multiple times while I am sleeping (which we argued about since I didn’t like the double standard and he has since stopped as far as I know). And regularly watches tik tok or shows and stuff on my phone if his is dead. Which is another part of where my frustration comes from.

Any advice is wanted!
