I have a brother that is the same sitch for the last 4 years and he felt exactly the same after thinking about giving up that much time. That being said he made a commitment to making every second of that 1/3 time meaningful for him and his S and has been very satisfied with how his son and him have not missed a beat. His real success has been giving up any resentment towards his wife and she has noticed and often asks if he can take S additional weekends and days where he always says yes.
Wish you the best in your sitch and keep working on yourself, make you a better person and live the best life that you can. It will be tough but brother keeps me going saying now 4 years after D he has met someone else and is happier than he thought he would ever be.
