<human>: Can you give me a shortened version of the text?

So my girlfriend and I split up two weeks ago. We worked, hung out, and slept together every night for a year and a half. Obviously, we needed space, we were just too comfortable with each other. So while being intoxicated she gave me the bad news. I understand she still has some growing up to do, only 20yo, so it was a mutual understanding. Now that I'm sober it's definitely sinking in. I work at a desk right beside her. I want to give her space to miss me. She's going to the gym, quit smoking, getting more responsible, it's the most attractive I've seen her. My co worker is actually trying to hit on her, a lot of dudes I know are.
<bot>: gf wants to change and grow apart, can't give her the space we needed to miss each other. Help!
