the man i hoped would be my husband suddenly ended things

assalamu alaikum, i dont really know how to explain this but we spoke for 7 months. he seemed so sincere, kind, religious and respectful, and never crossed any boundaries. we were in the same class in secondary school, but only properly started talking after he spotted me on the bus one day and checked how i was doing. i honestly wondered if Allah had brought him into my life when i was feeling so lonely and wondering if anyone would ever love me in that way. it was easy to get to know him since we were at the same school from ages 11–16 and we also live close to each other. we discussed how we might make things halal and i had never met a man so similar to me in such a comforting way. we didnt commit zina or anything like that, and those 7 months were probably some of the happiest of my life. i stopped feeling so alone because i thought he was by my side. i only have a few close friends, no siblings and one parent at home, so my days can be quiet and lonely. but now, out of nowhere, he told me he wants to end things because he needs to focus on work and uni, and he isnt sure he ever loved me or wants to make it halal. i feel completely blindsided, though i dont hate him - i admired how driven he was and never wanted to be a distraction from his goals. it just feels strange that it ended before we even had an argument. i feel a bit down because i truly believed he was the one written for me and i worry i might never love another man the same way, or that i wont find someone like him. i keep blaming myself, thinking i ruined it by being so happy and excited that someone seemed to love me. now i’m hesitant to get to know another man, afraid of being blindsided again. it’s not a priority right now since i’m also focusing on uni, but it’s something i think about for the future.
