<human>: Wow. I don't know where to begin. I'm 36. She's 27. We have an 8 year old son. Our relationship has been up and down for the past few years. She used to live with me. She moved back to her parents house last year. I called her to see what she was doing tonight and she said the usual. Go shoot pool. She's been hanging out with other people while we frequent our favorite hang out so I didn't pay any attention until she started kicking back with one dude. I straight asked her what the fuck was up with that shit and all she said over the phone was "you're the same. you're never gonna change. I've changed and I want to be single and go out and have fun". I admit I've been slightly distant but I've always been here for her. It's over now. It's only been a few hours since that conversation and now it's starting to hit me. We have a son together but I can't help but feel anger and sadness. I want this relationship to work not only for me but for him as well. This was my fourth relationship in my life and it lasted the longest at almost 9 years. I can't but help feel pathetic that I couldn't save it. Fuck. My mind is racing that I can't really even have just one emotion to focus on. I hate this. She was my best friend and I can't even go to that person to say what I feel. I am lost.

I know it's not the end of the world but this fucking sucks. A part of me feels like dying, the rest of me vows to continue on. 

Anyone have any positive words or can you please give me advice? I am hurting and I don't know who to turn to. I've always kept stuff like this to myself. Maybe it's not healthy emotionally but that's just the way I am. Anything to help?

Can you provide a brief rundown of the text in within 3 sentences?
<bot>: My SO broke up with me over the phone today. We were together for almost 9 years. We have a son who is 8. I don't know what to do.
