X.O.
I had been dreaming about moving my family home to Minnesota for years, so much so that I didn't invest any time in making friends and becoming part of any communities here in the Chicago area. I kept trying to convince my husband to move to MN, as I have a HUGE family there (27 first cousins), and a ton of friends.
I made him feel so guilty about staying here, but I didn't even stop to consider how frightening it is for the sole bread winner to uproot and transplant, and how much income we'd lose out on in the process. It wasn't until one day that my husband flat out explained to me that he worries about being able to provide for our family (and his parents), and can't afford to leave his practice, which he has been building for years, and start anew elsewhere.
Finally I resolved myself to the fact that our family is going to stay in the Chicago area, pretty much for our whole lives. Once I was able to do that, I was able to focus on finding the best possible community for our family. We researched and chose a church, school, and area that we want to live in. I've made a few close friends, and many acquaintences who have the potential of being close friends. My closest friends here are also transplants, so we've become like family--we spend some holidays together (when we don't go visit my family in MN, hubby's family in CA, or host family.)
You seem to be family oriented, but as my husband had to remind me, your primary focus needs to be your CORE family--you, hubby, and kids. It is wonderful that you want your kids to be close with their cousins, but you're poised to sacrifice their relationship with their FATHER in order to do so. That's not right. It isn't fair to your husband or your kids. What is it to gain some cousins if you lose your dad in the process? Poor consolation.
How often do you visit your family, or host them? I suggest trying to increase the visits, as that will help you cope, as well as afford your children the opportunity to be close with their aunts, uncles, cousins and grandparents.
