Is there reward in leaving someone I love for my parents' sake?

Assalamu Alaikum. I'm really struggling and need to let this out. I met someone and fell deeply in love. He was a police officer, high rank, good income here in Canada. Early on, he told his mom about me and she liked me right away. He was everything-kind, manly, funny, caring, and practicing his deen. He even went for Umrah and brought me back a prayer mat, dates, and gifts, so I felt he was serious. I prayed Istikhara and felt peace about him. I first told my brother, but he immediately got angry and said no way. Turns out, my brother had a fallout with his brother back in university, like 10 years ago, and he never moved on. Also, my guy was my brother’s supervisor once, and my brother thought he was arrogant and talked too much. My guy had a past relationship but it ended because she was unfaithful, and I was fine with that-even his mom knew about it, but I didn’t see it as a huge issue. I kept seeing him anyway. Then months later, I told my mom, and she wasn’t pleased either. She focused on how he only has a business degree while I’m an engineer. She saw his police rank and his mom being divorced as a broken family. And of course, my brother added his grudge to the mix, so she disapproved even more. Both of them freaked out, yelling and fighting with me, my mom crying and guilt-tripping me, saying I deceived her by finding someone on my own and telling her so late. They said awful things about him and forced me to end it. I even met his mom, and they encouraged me to fight, but I just couldn’t take the pressure, so I broke things off. It’s been six months now, and he’s still on my mind constantly. I have no interest in anyone else. My mom brings other proposals, but none of them make me happy like he did. She has a lifelong habit of guilt-tripping me-nothing I do is enough, she calls me bad, curses me, and says I have ill intentions. She only cares about showing off to her friends, so she wants a doctor or engineer son-in-law to brag about. My dad doesn’t know any of this, but I’m sure he’d accept whoever I choose. My mom warned me not to tell him, claiming he’d be hurt that I went behind his back. But honestly, my dad would support me. Problem is, my mom dominates everything-even yells at my dad and fights him-so I fear she’d sway him. The guy I loved even urged me to talk to my dad, but I never did. Now I’m mentally drained, crying to Allah daily. I miss him terribly and wish I could go back, but I’m terrified of breaking my family apart, seeing my mom cry, or being disowned. She cries over little things these days and fights with my dad a lot. Friends say I’ll find someone else, but I’ve been patient and tried, and he’s stuck in my heart. Should I just wait and ask Allah to remove this feeling? Should I reach out for closure? I feel so guilty for breaking his heart. I’m suffering and feel so alone. Is it better to keep peace with my parents at the cost of my own heart? Will Allah reward me for this sacrifice?
