<human>: Can you succinctly summarize the text in 1-3 sentences?

The person I loved most dumped me before Christmas. He's shacked up with a girl 10 years younger than him. I'm in my late 30's and childless because he delayed having children with me and then dumped me at crunch time. I hate him so much. He's wreckecd my life, it will never be the same. He didn't only break my heart, he also tore up the lasrt shreds of my faith in humanity. He knew what this brreakup would do to me, but he nevertheless did it in the most painful and humiliating way possible. It's so painful to know the person I invested everything in, and who once loved me very much, can just throw me on the garbage heap and walk away. If that can happen what is the point of love? 

I have never hated anyone like I hate him now. I'm riddled with hate. He absolutely makes me sick. But I can't show him this! We're trying to do an amicable divorce process and I need to keep him happy and calm. If we get into a power struggle he will burn through every penny we have to beat me. It's killing me that even now I have to tend to his feelings over my own, but there it is.
<bot>: Gotta tell the world what a sefish feckless profligate solipsistic and generally stupid guy my ex is, 'cause I can't tell him.
