You need to cut her off completely.
She is a succubus - she is going to take and take and bleed you dry.
Cut her off, seriously. Change your number, your locks and dump everything of her's out the front for her to pick up.
Go see a lawyer.
This may be difficult, but it is the best approach.
You have do understand that it is over and it is time to make a clean break from this situation.
Get rid of anything you have that you associate with her (gifts, pictures, and so on). Getting rid of the physical things might be the easiest part, because at least in my experience, bitches don't get you many gifts. But think about all of the money you have probably spent on bitches throughout the years...what a disparity.
Next, cut her out of your social media, maybe delete your social media altogether and stay in touch with friends and family through the phone, and that old fashioned way, in person. If you are able to, change your phone number, get a new email, etc. Delete her contact information. Whatever you do, don't seek her out in social media or anything like that. It might be hard to do, but it will only prolong the pain.
Most importantly, confide in friends and family and seek help. Not sure how it works in the U.S., but in Canada, even a visit to your family doctor can help you get a referral for counseling. It seems that this may be beneficial for you beyond this particular matter.
If you are married to her or were living together, this all gets a bit more complicated.
Look at this as an opportunity for a fresh start and the opportunity to do things that will help you become a better person. Stay strong. It may be difficult at this time to look at things rationally and see that there is absolutely no reason to harm yourself over something like this, but that is the absolute truth.
