Hi, I am sorry that your husband left and can't imagine what you are going through. He is selfish and inconsiderate of you and your children. I hope that your children are surrounded by people who love them and can spend quality time trying to reverse his damaging and demeaning acts. As for your teeth, I am hoping the information I have is going to work for you. Im not sure how far you are from this dental school, but it has very good reviews and is in Mass

You have to NOT have a regular dentist to go here and I think I read the emergency room fee is about 80..Im not sure what all they do but since I have been to dental schools in the past, they are pretty much the same, they take forever, they are students and learning and the professors have to sign off on every procedure. With that being said, they are also much much cheaper than dentists so hopefully that makes it worth it. This particular school has very good reviews and I am hoping they can help you. As for your husband, if he is still working somewhere, I would file for support..ASAP if you already haven't. I used to think my ex didnt have any money because we lived very frugally..turns out he was hiding/saving it all and a simple asset search showed he had saved over 250,000 in our 7 or 8 years together. Needless to say, I was awarded over 70,000 of that money..you never know..at least try to file and see if he has any hidden assets you and the kids can live off of. Worst case, draw medicare/medical, foodstamps, etc and let them track him down to pay for it, its the least he can do after leaving you in such a slump. Take care and I hope you get your teeth fixed. Best of luck to your family.
