Hi adriana- I am so sorry for your pain and what you are going through. You have come to a very good place to get support and advice. I am no expert nor do I have enough information to tell you if your H is having a MLC. If he is, hold on to your hat because if you want to stand for your M, this is one long and bumpy ride. I'm not going to say this to be mean, but if your H is having a MLC, you can pretty much count on the M that you knew to be over. Now that does not mean that your marriage can not be "restored" but MLC takes time...lots of time...and lots and lots of patience from the LBS but many MLCers do return.
Right now you should read all of the resources here and on other websites. Go to your local library and find books about MLC. They will all tell you to detach, GAL (get a life) and try to have a PMA (positive mental attitude). Move on with your life as best you can because this not only helps you make it through each day, but it also prepares you for a future that may not include your H.
Now, with all that being said, it sounds like you should be contacting an attorney if your H was the major bread winner of the household and he has cut you off. If you do contact an attorney, try to find one that understands that you want to save your marriage. A lot of family law attorneys out there just want to bill whatever they can so they will press the D.
