Woodbridge or Cheshire (husband can park in New Haven or West Haven for Metro North train). Or, maybe Guilford or Madison with Shoreline East train to Metro North to City.

OP’s likely going to drive to/fro Boston (or, Riverside or even Framingham MBTA commuter rail lots), and want to find place to stay 1 night/week. Suspect OP or husband may end up searching for new role within year.?

Towns listed above have good schools, and enable convenient access to New Haven, good restaurants, theater, Yale museums, etc). Milford, not quite as well respected also a possibility. Good luck OP.
