Needing some advice ladies...

So I have just found out I’m currently 4 weeks pregnant, super early days, and completely unexpected. Both me and my partner are in our early 20’s and he already has another daughter from a previous relationship. Him and his previous partner have some issues so he doesn’t get to see his daughter very often and there was a lot of drama around the birth of his daughter as she was also unplanned. I was so excited when I found out we were expecting as I’ve always wanted to be a mum, but he didn’t react very well. He was quite upset and made it clear he wanted me to terminate the pregnancy. He made good points which I agree with, such as we are only young, our financial situation isn’t overly great right now and we are currently in a rental. Although I’m pro-choice, termination is not something I would be able to do, regardless of the situation. I feel as though we would be fine welcoming a baby into our family and that we have quite a while to sort things out, however he doesn’t agree. I have said to him that if he doesn’t want this baby, I will understand if he wants to walk away, but he doesn’t want to do that either. Anyone had a similar experience and have any advice? I don’t know what to do. I’m feeling guilty for wanting to be excited about this baby. And if our opinions both don’t change with time, I don’t know where to go from here.
