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

I feel broken and betrayed. We had been together nearly 5 years. She had cancer and I stayed with her through it. 

She had dumped me a month ago and came back to me saying it was a mistake. She said I was the only person she could see as the father of her children.  I took her back. I got comfortable again. Then I offered to take her on a date just the other day and she began sobbing. I got it out of her that she was interested in another guy and doesnt want me anymore. She has felt like this almost 5 months now. I feel so used.

Ive never been in a long term deal before her. I feel cheated on. She said she has done nothing with him but the hurt is the same. Ive been so angry lately. Ive smashed a wooden door with my flesh and bone. My knuckles are bruised from punching concrete. I think she is scared of me now, though I would never lay a finger on her. I smashed many of the presents I gave her over the years. I felt really bad about that. I gave back all the gifts she has given me over the years as well. Especially her pity presents over the last month.

 I can barely eat without wanting to throw up. Ive cried more in five days than I have in five years. Just sleeping in my bed is a mocking reminder of my inadequacy. I already had such a hard time learning to trust people, but now I feel like theres no reason to let anyone ever get close to me again, if anyone even would. I dont mean to be disparaging to women but I truly feel like I will never be able to trust a woman again.

I dont know why I am posting this. I just need to make it into words and scream into the abyss. I was already on a serious downswing in my luck, now I feel like Ive lost everything. And I still have to see her constantly since we share a house.
<bot>: long term GF dropped me for another guy after lying to me about wanting to be with me. Now I just feel riggety-riggety-wrecked.
