Horrible baby father

Now I will be brief, I'm 17 weeks pregnant and I'm not getting any attention from my child's father. He wanted this for years, but now that it is happening , he is MIA. He doesn't call to see how I'm doing or anything. At first, I was extremely heart broken, but now I'm like whatever. I've decided that if he does decide to be involved, I don't want nothing to do with him. He's not invited to the ultra sound, baby shower, or delivery. The child will solely be named by me. I don't feel that he is worthy enough to be involved. I've been open to date other men. I've been contemplating on whether I should tell him about the decisions I've made, or if I should wait until the time comes. What do you ladies think?
