I (25 m) and my gf (25 F) live together with her sister and my two sons. We have been living with each other for about 7 years and we are struggling financially and just getting by as far as affording food for ourselves and paying bills with everything getting more expensive nowadays. Of course her and I have had ups and downs but what relationship doesn't? I'm just putting this piece of information in here because the moderators won't let me post without it.

Nevertheless, this morning I woke with severe pain n my lower left flank and was vomiting up yellow needless to say I have a kidney stone, anyway my gf comes downstairs to check on me and I ask her if there is any Pedialyte in the house I can drink to try and ease the pain a bit and rehydrate myself from throwing up since it has helped me in past with previous stones.

She said no and then I asked if Walmart was open yet because I forgot what time it was and she said "I don't know let me see your phone" then she reached down and just picked it up and asked " what is your password?" So I asked her what time it was and she said something like 2:30AM and of course Walmart has been long closed for the night so I said don't worry about it I'll just drink water.

Then she kept insisting that she wants to get in my phone to look for any stores open besides Walmart that would have Pedialyte and so I said no because obviously there isn't anything open at that hour that would have what I needed. You know, it's common sense.

She asked me why I wouldn't let her have my password and at that point I was in too much pain to be in the right headspace to give a logical answer so without thinking I said I just didn't want to. Now bear in mind that I don't have anything to hide I don't text other girls or anything related to that but I felt like the whole time she was trying to use my situation to go through my phone and therefore I felt like my privacy was being invaded a bit.

I told her this and how I felt after we got home from the hospital a few hours later and she said "well now I know where the trust lies in this relationship". I didn't know what else to tell her after that and I was still drugged up from the morphine anyways so I just sat there in dumbfounded silence as she stormed out of the car and left me in there.

I understand she was trying to help but I never asked her for her password for her phone ever when I asked to go through her phone once in the past and I also feel that I have a right to not give out my password as to maintain a boundary of privacy because it's MY phone. I don't understand why she didn't just use HER phone in the first place to look up places even though it would have been a meaningless waste of time for both of us even if i did let her into my phone.

I feel like she was trying to catch me in some kind of lie and now she's mad that she couldn't get into my phone and now she's acting like I don't trust her and is acting petty to get me to fold and admit fault. I'm really not happy with her right now and I need some opinions on this trivial matter please and thank you.
