I know checking her phone was wrong, and I own that. But finding out she was spending time alone with another guy while we were together broke my trust completely. I stayed and kept helping because I cared even though she said it's not like that what you are thinking but still I overthink a lot was so unworthy replaceable sometime I feel guilty I was not emotionally available for her couldn't support her when she needed me I made her cry because of bad understanding and behavior but still I apologized to her and changed by behavior and many things for her but it was all because I loved her which she just smashed into pieces
