Welcome Reverof! I'm sorry you've had people in your life shut down your creativity like that, and I hope you can feel free to write to your hearts content here.
I read (most) of your first summery, and this is a big improvement already in presentation. Previously it felt like a stream of consciousness that both gave too much information, and lacked all of the interesting pathos and connective tissue that makes that information make sense! The new brief summery is much better as far as giving us something we can sit and wrap our head around. @Zaboem is right, though, and researching how to right a summery blurb, and how to write pitches would be valuable to you. =D
What really needs potential work is the pathos and character motivations. I think if I was going to give you one piece of advice it'd be to find a way for the main character to be more connected to the plot other than being motivated by his dead girlfriend. Right now you have a more or less standard sci-fi male power fantasy, and I think you can maybe dig a little deeper.
Having read bits of the other one, I can also say that it actually sounds like the dead girl friend had a more interesting story than our protagonist...
So you know, food for thought. Maybe you could wind her story into his story in a more integral way from the beginning, and still leave that reveal for the end. Might help avoid the "women in refrigerator" feeling, too. For example, either opening with a chunk of her doing whatever she's been doing, or have flash backs to her trying to execute her plan as BF goes through his stuff. And then show the actual results of her efforts at the end as previously mentioned.
But also don't get to hung up on making your plot perfect. Listening to advice is GREAT and please keep reaching out, and keep looking for resources to become a better writer. But also know that anything you write is worth it, because it got you excited enough to sit and write, and thats kind of a necessary part of becoming a better writer. Don't get psyched out or demotivated. Push forward.
