My husband has abandoned me and our 2 boys....................?

He left for a job, which expected him to go out of state. Its hard to get a job as a skydiving pilot especialy here in Florida, which he hates, so he felt he had no choice. He was supposed to leave the job because we decided we did not want that, but he didn't come home one night and I realized he left. He left on May 29, of this year, and have been gone since. Angry and hurt I called the job, trying to find out what was going on. He was mean to me at first, I guess guilt. But after a few days, he started talking about me and the boys moving there. On June 9, he was fired. He blames me, but I blame it on the way he does things. I guess they didn't trust someone with such erratic behavior. We havn't spoken since. He doesn't even call to speak to the boys, 5 yrs old and 9 yrs old, not even on father's day. He doesn't send money even. I've been emailing him alot, pleading with him at times to come home, sometimes angry. He said he will send money, but only $500/mo. He takes advantage of the fact I'm a pharmacist so he wont send much. I dont really care about that so much, I just want him to come home or at least call the boys. Whats the best way for me to get him to come home? Should I stop emailing him? Ignore him for awhile? He has done this before and came crying back.
