I think it all melts down to what your priorities are. It is true that striking a balance between work and family life is not as hard for a man as it is for a woman; however, sometimes a balance is not just possible. One thing is bound to suffer at the cost of the other.

One of my teachers, in her forties, a renowned medical consultant, decided to do a PhD. Her husband, already distraught with her busy schedule, said no. She would not listen. Result: she asked for divorce. She completed her PhD and got married again to another guy.

I have seen many a competent lady who would just leave their work for their personal life. And oftentimes, they do not regret it.

I believe the best is to listen to your heart. As for as your situation is concerned, I guess you already have five weeks fully to your yourself--- for work. The next five weeks, you can somehow squeeze in your husband in the schedule, if you love him. :)
