I Am Confused

I just had a job interview and it all went well but when my husband asked about it and I explained the the job responsibilities and what they are looking for and the possibility of working long hours and important meetings that may happen in weekends he wasn't happy about it and said that i should think of the kids and long hours for a mothers won't be appropriate.. that got me so confused.. is it possible that I will be blamed for being away from home if I started a career no matter how many hours I work?... we did speak about me going back to work and he was incoraging it but this time I am not sure.. if its actually the long hours or something else... I shouldn't take what he said serious at this time since its the time of the month where .. you know...I didn't comment on what he said I just paused... and yeah am not offered the job yet but... My question is...its been 4 years since I took a break from work to raise a family but why does it seem complicated? ... would really need some advice now...I am not sure whats expected from me.. what am I expected to do in these coming years...
