So today my boyfriend asked me to watch his phone while he was outside to wash his car and I was looking through his phone to see what was said between his cousin and him because he told me that his cousin is planning to propose on October 9th to one of my friends. Both of us do the same thing, if he wants to know something he looks at my phone and we have an open door policy about that , it is never about distrust or anything like that just to clear the air so you dont think I was snooping. Anyways, I found the details of what his cousin was planning and then I was completely caught off guard when I saw that he had put when he was planning to propose to me in November on Thanksgiving. I feel horrible because it was completely unintentional and I wasn't even looking for the information and now I don't know what to do. I didn't want to know when he was planning to propose to me and now I feel like I have ruined my own surprise. I feel weird telling him because normally we look through each others phones and its not a big deal at all but in this case I don't want him to think I was snooping trying to find out because I wasn't that at all. I don't want to tell him and him get mad at me but I also don't want to know the date he is planning to propose. What do I do??
