So I work 80 hours plus per week and have been seeing my LTR less and less. I got a little suspicious and decided to check her phone, something I've never done but suddenly felt like I needed to. Didn't find any hard evidence of cheating, but found large sections of conversations with guys that were deleted, a conversation (half joking) about her ex roommate setting her up with her new roommate and how they changed numbers etc. Is this grounds for goodbye?

I confronted her about the missing convo pieces and she claimed that "it was her complaining about how much I work and them telling her to break up with me and her saying oh no I could never do that" if that's really the case, not sure why she felt the need to delete, and I also tend to not believe that at all.

As far as her roommates roommate, she says she doesn't like him, awalt, i don't believe anything she says.

Any advice here? Feel like I know the right play but bad at taking my own advice
