S.,
I wonder if it isn't the fact that you are going back to work that bothers your husband, but the *type* of work you want to go to. I don't want to be a wet balloon, I know it is your dream to be a cop, but think about your son. What would happen if you were shot one day and he had to grow up without a mommy? Sometimes, when we become parents, we have to wake up to a different reality, a different set of responsibilities. You cannot just think about yourself anymore, now you have a son to think about. How would his life change if you were not there? Who would your husband select to raise him? It's harsh to suggest, but if you truly want to be a cop, you have to ask yourself these questions.
I am not suggesting that you continue to be a SAHM, because I am not. But I do think you should reconsider what you want to do. Perhaps you can do something in the criminal justice field that does not put you in harm's way every day. Maybe go into social work, or some other field that does not jeopardize your life.
Unfortunately, too many women today don't respect their husband's authority as the man in the house. I'm sure he is not trying to squash you - just concerned about you being a police officer. I would not "keep myself available" to be at his beck and call - I agree he should try within this year to find a job that does not require him to travel as much. But I would reconsider your personal career plans as well, and maybe find solutions for both of you.
Some things you could do that are a little safer include being a park ranger, you could work in the court system as a bailiff (no guns allowed in the courtrooms!), you could work for the Attorney General - do a google search for CJ careers and I'm sure you will find many different, safer opportunities out there.
