New York?

My husband has recently been offered a position in Long Island, New York through his current employer, and it has thrown my mind into a tail spin! While I'm excited at the opportunity to live in Long Island, so close to Manhattan, I have a lot of apprehensions. My entire family lives here in northern Illinois, so it would mean moving away from all of my loved ones. I have also lived in 5 different places in the past 7 years, so I'm a bit burnt out from moving so much. I have also yet to really make a house a home, considering I've only been in one place for a little over a year at a time.  But I think the biggest variable that is affecting my ability to just pack up and go is that my brother lives in California, which means both of my parents kids will live in opposite sides of the country if we go. It really bothers me that we would both be so far away from our parents. Not to mention, my daughter is 16 months old, and it's very important to me for her to be close with her grandparents which will be nearly impossible if we move.

On the flip side, though, My husband has always wanted to live in or near Manhattan, so there is part of me that really wants to make that happen for him. I had an opportunity to live in Miami for a few months about 5 years ago. I was all set to go but backed out at the last minute. It's the only regret that I have in my entire life, and I'm afraid that if we don't take this opportunity it will just be another huge regret. Also, this could be a great opportunity for my husband to advance in his company and we might be able to move back home in a couple years.

So, obviously we have a lot of thinking to do and a huge decision to make. Any advice or words of encouragement would be much appreciated !
