What to do?

Not really controversial, but I am leaving my BF who I have a two year old with because he just decided he didn't want anymore children. He did before but not now. *its the hardest decision I have ever made since I hate having to split up my son from either of us. Also my sons father wasn't very nice too me :( 
Anyways, I own my own home and could barely afford payments on my own(BFs name not on home), so do I get a roommate or get rid of my car to help with extra money? (I'd get something less expensive, my car payment is $450 a month) problem with roommates is I don't know or have any friends near or in the town we live in and do not trust "strangers" coming and renting/living with me and my child. And my car, I spent a ton of my savings, over half to pay towards my car so hate to throw it away. I have two years left to pay on it
