My boyfriend told me about a girl back in Brasil

I am (f19) my bf is (m 18)
And we have been dating for three months.
He didn’t cheat or anything.
Context my boyfriend lived in Brasil his whole life, when he was 14 his family had to come to America because his dad got sick here during Covid.

My boyfriend and I were just smoking on the patio when I asked him what us was like moving to America, he told me how it was moving but he also told me a story about a girl.

This girl and him were just about to start dating when he had to leave, he talked about how sad it made him and how she cried.

For some reason ever since the moment we started dating I have always felt like he deserves someone from his culture or at least someone who isn’t a Jew. But I have been able to get over it and not think too much about it.

But for some reason his story last night broke my heart. Not because I think he doesn’t love me but because what if they were meant to be together or maybe they would have had a great relationship.

I don’t know I guess in venting but I guess a part of me wants to break up because I think he deserves a women like him or at least not me.

Anyone who took the time to read this thank you. I feel like I can’t tell anyone this but I needed to get it off my chest. I love my boyfriend he is great but I guess I’m randomly insecure about weird things. Things I never ever thought about before. I also never really dated to this is all new.
