<human>: Give me a shortened version of the text

Me and my ex have been broken up for about 3 months now after a long 2 years of just clinging on to the smallest of hope and pushing on but it just ended recently because I lied to her and I completely understand her leaving and took it on the chin. 

Even though I hurt her, she seems to have changed in every way. She was always an innocent girl and was never one to sleep around but since we've broken up she's been using dating apps purely to find sexual partners, she's slept with a family member of mine and when we talk her emotions are extremely volatile and heated. 

I'm not over her really but I understand that i'm not right for her cause i'm still immature but she loved me with everything she had and I know her better than anyone. I know what she does these days is nothing to do with me, and I'm happy for her, but i'm struggling to come to terms with how she's acting and I dont really know how to take it.

I don't want her back, I just feel like I need to know what happened to her, is she hurting? Is she broken? It saddens me watching her turning into something she said she'd never ever want to become :(
<bot>: Broke up with innocent sweet girl, turned into a complete different person, feel bad for her and need to understand whats going on with her.
