Do any of you have long moments with your SO's phone alone with you in the same room...wanting to check if anything has changed between you two, but you're scared of what you might find? I've been alone with his phone for over 3 hours while he's helping his sister's fiance with their car...I've had plenty of time to look through everything without him coming in to catch me doing so. I don't think I have the heart, let alone the strength, to do it. I have this gut feeling (which has never wronged me) that my former friend is trying to pull him away but I can't find it in my heart to try to look...I honestly can't. I'm hoping my gut feeling is wrong for the first time...I'm so hoping it's wrong...
