DVM, I'm only gonna say you should focus on your degree. Becoming a doctor in any field of study was in the planning stages years before you were accepted as a student. Remember your goals and he will work on his. I am currently working on mine with my wife of 21 years leaving us ( I have 3 kids ages 17 to 20). Its tough for me to focus on getting my life back together and I'm not even in school. I know how hard it is for you in more ways than one.... My wife left because of alcohol and my father was a veterinarian. Its tough enough getting through the vet program let alone juggling a good relationship without hangups. Let him do his thing and you do yours, atleast until you complete YOUR goal. A big hug and reassurring smile to you....now go get that doctorate, you'll be glad you did!
