<human>: Can you give me the gist of the text in a nutshell?

My boyfriend and I have had our issues in the past like most. We decided shortly after we moved In together that we would make passwords known to each other and be open, and COMMUNICATE. 

Here is where I am struggling because it started about a week ago when I noticed his computer was shutting down when he walked away, this happens because when his phone leaves his computer it locks the computer to avoid anyone he didn't want to get into it, on it. 
I brushed it off because I knew the password so no biggie, we live with two other people. 

Well fast forward to yesterday when I get home from work and he goes to take a shower, I went to go send myself a picture and because he took his phone into the bathroom his computer locked, I try to log back in and his password was changed....
 Now here is where it gets extremely frustrating, because he did that I locked my phone with intent to unlock it in the morning he didn't know this. 

However, I like to make sure his phone charges every morning and well, I go to check the battery life and out of curiosity try to slide the unlock icon up  to see if he locked his phone..... Sure enough he did. 

I feel completely pushed out, and. Hurt. I do not know how to address this. Because doing this without talking to me just is a huge. Fat f-you, and you dint need to know what I do..... 

How do I address this?
<bot>: my boyfriend after two years decided that he wants his "privacy" and locks everything with a password, his computer and phone.... I don't know how to respond other than shut down.
