How can I get my bf to realize he's selfish?

I have 2 chidren from a previous relationship & a 2yr old with him. He doesn't have a license so his car was in his friend's name. He got pulled over & said he took the keys without asking(to keep his friend out of trouble), so he lost his car. Last yr he was pulled over in my car(I was working 7 dys a wk & was too tired to haul him around.) He threw me under the bus & told the cops that I let him drive it & knew he didn't have a liscence so I was arrested, got a hefty fine, lost my liscence for 30 dys, & had a boot put on my car for 30 dys. He wouldn't help me pay for any of it because he said it wasn't his responsibility to. He won't help financially with my oldest 2 because he says it's not his responsibility to. I can count on both hands how many things he has bought for the 2 yr old that we share together. We each pay half of the bills & rent, but he doesn't help with anything else like toiletries, diapers, furniture or anything. The only thing he buys is stuff for his xbox. He has three & MANY accessories & he also bought the router so he can play online. Even tho he makes more than me. Since I was arrested I take him back & forth to work everyday(so I don't get in any more trouble.) He puts gas in the cr, but won't chip in for repairs because it is MY car & it's not his responsibility. He ignores me all day while he plays xbox & then goes to bed & sends a txt asking for . Of course I said "No!" He got mad & unhooked the router & hid it because I was watching netflix thru it. He said that if I was going to act like a b@!%*, then I couldn't use his stuff. So, I went back to the bedroom & asked him why it was ok for him to sit on my bed, covered with my sheets, laying his head on my pillow, snuggled with my blanket, & watching my TV(I paid for them all.) So, he said that I was being selfish & making him feel like this isn't his home!? He couldn't understand that I was just showing him how it felt because he doesn't think what he did was selfish at all,but he thinks what I did was. How can you make a person this selfish see that they are SELFISH?
