Pregnant and abandoned #3

[blindsided1]

Ok. Another question. I'm starting to feel kind of angry. I have been going over in my head what H has done, specifically the way he did it (cheating, leaving me at 6 weeks pregnant after we tried fertility for months, moving in w/OW he barely knows). How he doesn't check in on me and the baby to see how I'm feeling or if there has been any issues. He only calls me when he needs money or sex. He is living in his fantasy world where he is sooo happy and left me to deal with the bills and the heartache and the pain. I'm getting pretty pissed. So, at this very moment, I don't want to have anything to do with him. I don't want to talk to him, I don't want to see him. I'm really hating him about now. So, here is the question: when he calls or texts, do I ignore it? What if it's something I can't ignore, my first instinct is going to be to get angry. Everyone says that I should stay upbeat and act "as if". Isn't that re-enforcing the idea that he can treat me like crap and I'll still be happy and upbeat. He never has to be accountable for HIS actions? I don't understand how this works.
