Stupid car

ARG!!!
When my ex and I split our agreement said that he would take care of his car and I would take care of mine. Pretty standard. But (because there is always a but) his car loan is in my name and his, mine first (my car is in mine and my dad's so no prob there). We did not title his car in both names so basically we are co-debters but not co-owners, I have no claim to the car.
It all started out well, he paid for his car but that didn't last long. He was a year into the loan when we split, I have been getting calls from the loan people for 2 years b/c of late payments or non-payments. The worst part about all of this is his payment was $225.47 a month. How cheap is that?????????
The car was a lease thing and when we bought it we planned to buy it out right at the end of the lease. He still wanted to do that but when you don't pay they will not give you another loan. The car was supposed to be turned in 4/15 and he did NOTHING for it. Again I started getting calls.
Well it turns out the car wasn't moving b/c someone had tried to break into it and had messed with the ignition. He let it sit for months, didn't call insurrance or anything.
I went to the dealership to ask for help, the know the situation. My mistake was not following up on it b/c the captain did NOTHING to try and keep the car. I finally got him to tow the thing into the shop so they can fix it and he told me he called his insurrance turns out that is all a lie!!! I don't even think he has insurrance. So who is going to pay for this??? Where am I going to get the money to pay for this? I don't want to ask my parents for money I am an adult. I paid off a credit card this year, I was so happy to have that done but it looks like I am going back in debt to pay for his pure laziness and stupidity. I am sooo mad right now that I fully intend to get all of this in writing and take his happy ass to court for #1 contempt and #2 to get my money back. This is not fair, I know life isn't fair but I didn nothing to him. I took my debt when I left, I helped him out even. How could he be so irrisponsible????
I cannot wait for him to go to Georgia b/c I cannot stand looking at him, the thought that I am going to have to talk to him today is horrifing. My son is going to be around so I am going to have to be nice. I do not want to be one of those parents who bashes the other one but I am sooo almost there. I am soo upset right now!!!!
I am happy that this is the last tie I have to this man finacially but so pissed that he cannot take care of his business and leaves it up to others to take care of. Then gets mad if you "judge" him. Well what do you expect? Do you think that there is a magic fairy out there that is going to come over and take care of you? No you mo-ron that is not the case, you need to step up and grow some balls!!!
