The women I meet in Portsmouth have all been married for 20 years. I met several young single guys on dates who drove up to Providence for any and all dates. They didn't have amazing things to say about Newport either other than they drank a lot at bars (but this was several years ago so maybe things have changed). You will be driving up to Providence for probably most dates/young person activities, just fyi. Some locals will consider that long distance for a relationship, as absurd as that sounds, so it may limit your options for relationships.
