Treading water

Ok guys I need some opinions.
W interview went well. The new job (if she gets it) will have her traveling some. She has always been the one to take the kids to and from school. If she gets the new job then this will probably have to change. I am already at work before the kids go to school. She asked me if I would be able to change my work schedule to accommodate her schedule. I likely could but i don't really want to. I have a really good work schedule. My thought is if none of our issues were going on then I would not hesitate to go in tomorrow and change my schedule. However, if she is going to leave after she gets the job then I don't really think that should be a priority of mine. W and my girls have always been my number one priority and as I said before it wouldn't be an issue to change my schedule if all of this other stuff wasn't going on.

My answer was " honey, I will do what needs to be done". Said in an honest caring tone.
I know this will come back up. How should I answer it in the future? Essentially, I would change my schedule if we were going to stay together but I am not sure if that is what I should do if she is just going to leave once she gets her new job.

Thanks in advance for the input.
