Breakup Truth - Part 1

I've been in a relationship with this girl for almost 2 years now. She had broken up with me 4 months ago because her mom hated me as I wasn't doing to well career wise. We got back together a 2 months after the break up. When I tried getting more clarity about the break up she always gave me blanket answers or gets really uncomfortable and changes the conversation. A while back she told me that she wants to tell her mom that she's back with me. This didn't make any sense to me as her mom was the reason we broke up in the first place. We had multiple fights about it but in the end she ended up telling her mom about us. Last week 1 had a chance and I went through her phone(not really proud of this). The things that 1 found on her phone were truly horrific.The real reason why she broke up with me was because she wanted to peruse a possibility of dating her guy best friend. She had made a full blown pros and cons list comparing me and that guy a month before we broke up. (Continue on part 2)
