13 weeks and solo

So my child’s father has decided to not be in my child’s life. I keep thinking he can’t be serious but it’s been a month and we only recently talked once. He basically told me I chose to keep the baby so I am on my own. I literally begged him to not do this but he just ignores my long ass text. I’m so confused and don’t even know how to tell people. This is so embarrassing. Luckily I’m staying happy and positive for the baby.
