Is there any single mothers here?

I'm with my partner but it's like if am alone.

I honestly can say my emotions have gotten the best of me. I fear of being alone but I know for a fact that my partner and I aren't going to make it. He only cares for himself and you would assume "oh it's the mother of my child, I need to be there" no he's not... I've done a lot of things on my own so far and I'm only 13 weeks and 5 days. There's still a long way to go and i just feel it in my gut that it's going to be me to suffer. Just need someone to talk.
