SO Just Started Academy.. I Want a New Life

Hello All.. I'm writing because I'm desperate and on the brink of a breakdown. Let me preface this by saying I am a very social woman.. i work a creative job, have many of my own interests and have many friends.. but this situation is tearing me apart..

First off.. my husband and I have been married for 14 years and have no children (medical problems)... we married extremely young and have had more than our fair share of ups and downs. I would agree that we had no business getting married when we did. My husband spent the first 10 years of our marriage resenting the fact that he was "pressured" into marriage at an early age and acted out as a result. Late nights, infidelity, working an uneccesary second job etc. During the course of our marriage all I craved was normalcy.. I wanted to be able to have a normal/similar schedule as my husband and eat dinner every night together as a family. He made this virtually impossible by working a second night job for almost 10 years and not coming home at a consistent time on the non-working nights. In addition he hated his day job and suffered from low self-esteem...I deeply resented his working nights and begged him to quit but he didn't.. 

It all came to a head 2 years ago when his ways came out and he admitted to everything.
