Is It Actually Possible To Change My Name And Start Over In Another Place—if I Am Not Avoiding Taxes Or Other Debt? What Are The Potential Legal Ramifications?

I am stuck in a deeply unfulfilling marriage of five years and after trying therapy I am strongly considering divorcing him, changing my name, cutting all my ties, and moving someplace totally new. I do not have any debt. My car is in my name.

My questions are as follows:

1) Will this inhibit me from getting a job in my field if my legal name is different (I’m a teacher) as in, will it be considered fraudulent if my resume states that I earned degrees when my diploma has a different name? 2) if I remarry someday, how does this work with acquiring a marriage license? 3) Are there other pitfalls I am not foreseeing?
