So I opened up instagram on my desktop, I usually use my phone, I didn't realize her login info was saved.
Of course I probably shouldn't have done this but I logged in and saw their communication over a period of 2-3 months. It gave me the perspective of what someone going through a crisis looks like. She had way more fights with him than she did with me towards end. She was having the same problems she complained about with our relationship, lack of passion compared to beginning, feeling like he's distant from her, her having the same pattern of fighting then wanting to be intimate. Her saying he's not the same as when they first met, a lot of this type of stuff. Basically she was already getting bored of not having the rush of a new relationship, him using his daughter as a way to manipulate her. Much of what I already assumed. It actually made it hard for me to because it felt like she is completely broken, also a lot of the fights coincided with her being nice and affectionate to me. It also reinforced to me that it was absolutely nothing that I did wrong and this is an issue deep inside of her. I have abstrong feeling that if and when this one ends she's just gonna try and reach for the high of a new relationship. It's hard to know that she's surrounded by enablers instead of people pointing her in the right path

This however hasn't changed my goals and drive to make myself the best I can be, hitting the gym a lot harder and have a six pack for the first time in my life, socializing more, keeping myself busy.
I just have a very strong feeling she's going to hit rock bottom at this rate
Frankly I'm amazed at how long we even lasted together considering how quickly she went in love head over heels with him and now he's already tired of her fighting with him and playing games.

It was an amazing eye opening look into the mind of someone so deeply lost.
