No worries, you have to balance and do what's right for yourself (career-wise) and what's best for your family (income, insurance, time off, etc.). You're doing the right thing, comparing what you've got right now and what you may have in the future. Leave no stone unturned in your research and continue to ask questions.

The time you spend with your family is irreplaceable, you will never get that back. As someone who as spent a large amount of time away from family, trust me in that.

Two times will really decide whether you made the right decision, every day you walk in the door home from work and the day after your 65th birthday. If those two times you can hold your head high and be proud of yourself, it matters not what else you've done.
