I realize you don't want to respond to what I've said about the drunk sex, and the drunk dialing, but you will have to address that as your responsibility in the situation in which you've found yourself. The man told you that the two of your were "just friends," probably how he saw it from a casual sexual alcohol induced encounter. You should not expect anything from him.
It's sad for you, that you became pregnant. Then, probably correctly, based upon what you have said about your own health, you could not have a child.
You had an abortion....a very traumatic exp. for you.
Now you must focus on recovery. This means letting go of any expectation of emotional support from this man.
