Are jews slightly unwelcoming to non jewish partners when it comes to dating?

Hi, I’m not religious, but I was born into a religion through my family and culture. In my background, we usually really value and welcome people who want to join, convert, or just share in the community.

Recently, I’ve been seeing a Jewish guy that I love, and things are going really well between us. I’ve learned a lot about his perspectives and culture, some of which gave me new insights into topics I used to see a bit differently.

One thing I’ve noticed, though, is that some other Jewish people (his friends, and even family) who know I’m not Jewish have been kind of rude to me. Sometimes they make comments that feel bitter or even mocking about our relationship. For example, i had one of his friends say that she thinks i should search for someone "elsewhere" and that she doesn't think our relationship will last due to different backgrounds. I totally respect people having their own preferences, but I don’t understand why they would try to impose those views on my boyfriend, especially since he’s completely comfortable with us being from different backgrounds.

This has made me wonder if this is just about the specific people he surrounds himself with, or is there a broader perspective in the Jewish community about not being welcoming to outsiders? I’ve talked about this with my boyfriend, but I haven’t discussed it with non-Jewish people because I don’t want to say anything that could fuel antisemitism.

So I wanted to ask Jewish people here directly, should I expect these kinds of reactions in general, or is this more likely just about his circle?

Sending love to you all
