I’d recommend living in Portland or South Portland and visiting OOB occasionally when the mood strikes. Portland is a wonderful city with lots going on year round. Your commute would be super easy. Unless you’re into the off-season boardwalk experience on the daily, not sure what OOB would offer you for a living experience that would be better than those towns.

That said, if you’re already locked into a lease, it’s not a big deal. The distance between them is not big and OOB will be a fine place for you and your family to spend a few months.
