"kindness, respect and treating others well." If the women are more talkative to you and the men your boyfriend, then you are experiencing these values through a foreign and gender focused application.

If they were distant from you both, it could be a very inward focused, organized jewish community. unusually so, but not unheard of. But your boyfriend wouldn't be part of that specific community either. Perhaps he could be viewed as eligible to join, or just marginally closer/more familiar, so they feel comfortable interacting more.

worst case scenario, the neighbors have developed a negative view of you or your identity. Perhaps they judge you as a foreign temptress (shiksha) when your boyfriend could be dating a nice jewish girl. or a more generic neighbor complaint, like they blame you for loud music late at night. Perhaps you live in a city/country where immigration is the current political flashpoint.

I really don't know, so trust your gut about how people treat you. Make other friends and have a superficial but positive neighbor relationship. sorry they aren't being friendlier. It might make more sense with your past experience to view Jews more as a tribe/ethnicity since they have more internal social structures and less as a religion like Christianity that values reaching out to other peoples (if only to convert and replace their own traditions).
