I don't know how to approach this, so I would like some advice, if you have any to give. If you don't, well, that's cool too.

My FI and I are best friends with a couple from church in the town where we go to college. They are amazing people, and we love to spend time with them. FI and I have expressed interest to each other about having them be our MOH/Best Man.
We had originally expresed interest in staying in our college town after graduation, but soon figured out that due to economic reasons, it is just not feasible. We will be moving home after graduation in May (home is on the other side of the state). The issue is that our best friends have now told us they feel it is "God's will that [you] stay in [college town] and we think you're wrong to ignore that call". Since that discussion in early February (a week after we got engaged!), they have stopped talking to us except in church, and we haven't hung out with them since.
I am very upset, and don't know how to fix this, or if I even can. Like I said, we wanted to ask them to be party of our bridal party (thank goodness we haven't yet!) so it's kind of a major blow.
CN: BFFs of FI and I (who we wish to be MOH/Best Man) knocking off friendship because we're not following what they think is "God's Will" for us.
Any ideas on what to say or do? Just confused...
