I'll try to stay brief, on 16th Mom abandons family of myself and son without a hug, note, or meaningful bye?

on the 16th of this month I had my world eviscerated and my perception of reality radically altered. Keeping in the spirit of being short and to the point. We got together on july 9, 2009. Ended up pregnant almost instantly (luck me!) and were technically together till 16th of this month when she left to go to the store and preceded to steal my car, with the baby seat in it, my last $100 and never spoke another word to me since. I know her and her new guy are in town and have done extensive background.... enough to find out 95% of everyone I knew, either knew she was previously sleeping around or they were a part of it. I still ask some to just admit it and they have the drive to **** my lady and lack the balls to tell me... I hate this world. Anyway, from what I understand (and I'm very upset by this) if she just leaves, it isn't criminal in the state of OK, so we filed for food stamps which now have to wait 3 weeks inside of just days for food money cause my lady went retarded. I have started paperwork for TANF and child support. I decided I was going to raise him. I initially thought she wasn't mine and now I'm 90% sure he is, it would fit into the whole "I FEEL TRAPPED" mindset and all She has done crap like this before and I get her father to buy my stolen vehicle to ease the burden on the family. MY TRUE QUESTION RELATES TO THIS.... despite every effort including the e-mail where I was raging and sounded much like a maniac... I can't seem to get her to contact me in any way to tell me, stop trying, an explanation, "i don't know what to say", basically anything, and at this point I have tried requesting, provoking, threatening, demanding, trading, etc. and still not one word. I KNOW SHE WILL STILL CARE EVENTUALLY cause she had two others and it rips her apart inside that she can't be a part of their lives like she wants... i'm guess those feeling led to treating me like dirt... I wrote her an e-mail saying I gave her 5 days to contact me back with 20 min. of an explanation of where we went wrong and I mean not recently starting with guy #1... The way I see it, if you can be with someone 2 years and they won't even give you 20 seconds of that 20 min. answer... then I don't care if they would die tomorrow, I can not allow you to send these gifts to your son because it isn't worth my 20 seconds to walk over and give it to him,.... am I beyond rational thought here? Is it fair that a (if you count time already pasted) 2 week period is more than enough time to say, "AIN'T WORKING OUT, PEACE!" BUT she is saying in her actions I wasn't worth a second of her time to help me understand anything. I was an object to be used, you get it idea... So am I being to strict?
