Both my husband and I grew up in Ohio, about 15 minutes from each other. My husband left for Tennesee when he was 16 and later moved to Arizona and on to Chicago, never to return to Ohio to live. I came out here back in 2001 (several years after he left) once we became engaged. All of our families are still in Ohio and now that we have two kids, this is something that I wrestle with regularly.
I grew up with my grandparents and was extremely close to them. So, I know the kind of bond that you are talking about and not giving my parents that kind of relationship is hard but we have decided that, for now, this is what's best for our family. So, we continue to build our lives in Chicago.
Thankfully my parents make an effort with our kids and see them about every 4 weeks, one way or another. Additionally, they have them for a week at Christmas time and then a week in the summer. While it's not the day-to-day intereaction, they have created their bond and are very close. In fact, my son talks on the phone with my parents every night for about an hour before bed. They play games together, sing songs and tell stories. My dad has gone so far as to take pictures of his room so that they can play I Spy. It takes effort but it can be done.
On the flip side, my husband's parents do not make an effort at all. In fact, no one does on his side of the family. They are excited to see us when they can but they don't come here and they don't call. To me, it's weird but it's just what we have had to get used to. My husband left at 16 and I have come to understand that this is just how they coped with him leaving and not making an effort to come back.
This is the sad part. My children have a lot of cousins, from my husband's side of the family. There are about 15 cousins under the age of 10 and they all get along really well. I often wonder what it would be like for my kids to grow up with that, especially since I am an only child. But, we have made lots of friends here and for now...this is where we are building our lives.
I should also mention that my husband has no interest in moving back to Ohio. I, like you, probably would have done so by now on pure emotion.
I hope that this helps. Congrats to your hubby for beating cancer. Only you guys can make the decision on what's best for you. Don't make any decisions out of guilt...you will only regret and resent.
Good luck.
