Baby #2 ?///

Having I bit of a hard time figuring out what to do. I have a 2.5 year old with my partner. He now lives 40 minutes away as our relationship turned south for a bit. We still spent time together every weekend and I have just found out I’m 5 weeks pregnant. He wants me to have an abortion and refuses to move back into together unless it’s at his mothers house in a caravan in the back yard. I don’t know weather having a second baby with him is the best thing or not? 

any advice on raising a toddler and a new born on your own. Or weather going through with #2 is the right thing..
