<human>: The past 2 months have been really hard for me. I lost my first real serious relationship and the person I cared about more then anything. Worst then that I lost my best friend. For the first few weeks we were still seeing each other occasionally and being intimate. I thought that there was still a possibility that we might have a chance. But then he told me he was seeing someone else, a friend of this who has had the biggest crush on him. I was heart broken I really thought that was some hope. 

Everyone says that I should move on and shouldn't be upset anymore, but its just not that easy. I think it's hard for me to move on cause I was prepared to invest and work at the relationship. To me our relationship wasn't just a relationship I saw a future with him, I was committed to him. Honestly I think I was just more invested to make us work then he was. 

The hardest part for me now is just missing him and realizing he doesn't miss me anymore. That after 3 years together it only took him 2 months to stop missing me, to not think about me anymore. Im sure having someone new helps him to not think about me or us but it still hurts. I realize that eventually this happens in all break ups with each other not thinking about each other anymore. I had just hoped and thought that I was more important to him then what it appears I am. The fact that he just moved on so fast to someone else just solidifies this to me. I really thought he cared about me and loved me and I don't want to think that he just stopped caring but it appears that's what happened.

I feel forgotten and replaced 

How could he just caring about me? After we had built a life together for the past 3 years. I wonder if he ever thinks about me anymore.

Can you give me the gist of the text in a nutshell?
<bot>: missing my ex still, he moved on to someone new after a month and I feel like he's just stopped caring about me at all and has forgotten about me.
