Deobandi and Barelvis

Asalawalekum reahmat ullahe waba rakatu, I’m muslim, 17 years old,I love a man who’s also Muslim and we both are Sunni and we both have been together since the last 1 and a half year but one day he asked me to end this relationship I asked him why he said because we are from different cultures then I said that we both are Muslim and Sunni then he told me you people are deobandis and he’s barelvi and his dad is against deobandis so his dad will not accept me, I want to know that is there anything like deobandi and barelvis? And I really love him with all my heart and because of him I’m not able to concentrate on my studies I’ll be giving aipmt next year and please suggest some dua so that I can get him as my future husband and please pray for me. Jazak allah
