The universe will always give you what you ask for, and invite.  You invite through your thoughts and feelings….your reality is your belief system staring you in the face.
If you emanate negative energy / lack / rejection it will ‘attract’ from the universe ‘more of the same energy’
What you expect is what you will get
Thoughts have energy
Negativity always manifests into physical reality 
Energy (from outside) will draw out “like” energy from within you; destructive energy from outside provides a catalyst for your own inner negativity to manifest in an uncontrolled manner, sometimes in violence.
