Is marrying a good person worth it if the in-laws are difficult?

Assalamu alaikum, I’m really struggling and need to get this off my chest. I grew fond of a brother from university, and after we told our families, we talked for about a year while finishing our studies. My parents wanted us settled in careers before making things formal, which we were fine with. He and my family hoped to have the nikkah soon after we got jobs. Once we started working, our families began talking, and we invited them over for Eid. That fell through because my household came down with the flu. We invited them again a few weeks ago. Before the dinner, he wasn’t on good terms with his family-they felt he was pushing them too hard about marriage and even thought I pressured him into it and into taking a job in another state. He’s the youngest, and his two sisters are older and unmarried, with no plans to change that. The eldest sister refused to come to the meal over some disagreement and demanded an apology, so only his parents and middle sister showed up. We still wanted to move things along despite the rift. Honestly, the dinner was a disaster. Things seemed fine until the end, when they unloaded on my parents. They said they don’t want him marrying for at least two years because he needs a master’s degree, a better job, and a house first. They spoke poorly of his character-called him angry, financially unstable-his dad even held past support over his head. They urged my parents to push me to study more. They bragged about their own kids’ education (the eldest, in her thirties, still lives at home and just finishing a bachelor’s; the middle, late twenties, finished her master’s and applying to law school, also at home). They stressed how they want all their children staying under their roof and that he should come back. They said so many unsettling things I won’t detail everything, but it left my family shaken. After that, my parents naturally didn’t want to proceed and started looking at other prospects. It took me three days to tell him truthfully what happened and end things, especially since his parents told him the dinner went well. He was upset about their behavior but refused to give up. I was surprised he wanted to fight for us, and since then he’s been trying to talk to his family, hoping to change their mindset. I’m not sure it’s working, but on my side, my parents disapprove of his family-and now him-though they’ve left the final choice to me. I’m so torn. I truly care for this brother. He has good character, no matter the lies his parents spread, and anyone who knows him confirms it. He’s consistent in salah, strong in deen, and we share values, morals, even political views. He’s always shown he cares, but his family is the opposite. My family thinks Allah showed us their true colors as a warning before any engagement, but I’m only seeing him improve. I feel stuck, losing hope, and don’t know what to do. Any advice would mean a lot. Jazakum Allahu khairan.
