Asking for guidance after a breakup - salaam

Salaam everyone, I (25F) was in a long-distance relationship with a Muslim man (23M) for 7 months. We both come from good families, met in person every two to three weeks, and talked about the future. He often mentioned marriage and children and said he saw me in his life. Our families even met, and everything felt serious. Recently my parents suggested doing a nikkah so we could be closer and keep things halal. Instead of being glad, he got scared and said he wasn’t ready for marriage and wanted more time to “get to know me.” Not long after that, he ended things, saying the distance was too hard and that he preferred to find someone local. The distance was only three hours, and I was willing to visit and make it work. I even told him I could eventually move to Tampa to build a life together, but he still refused. What hurts most is that he told my mother he loves me but felt he had to let me go because “it’s what’s best.” I can’t stop thinking about it and feel like he gave up too easily. I have a disability (I’m deaf and have Usher Syndrome), and I keep wondering if that played a part even though he always said it didn’t bother him. He said his life goal was success through career, marriage, and family… so I keep asking myself, why not with me? It’s been a month and I still think about him every day. I’m trying to move on but it’s really hard. To my brothers and sisters here: - Why do some men talk about marriage and the future, then run when it becomes real? - Do you think he left because of my disability, or was he just not mature or ready? - How do you find the faith and patience to trust that Allah has someone better planned when your heart still misses the one who left? JazakAllah khair for reading. Any advice or perspective would mean a lot to me.
