Feeling Distant and Hurt, Need Advice from Brothers and Sisters

Assalamu alaikum everyone, I’m in a tough spot and could really use some heartfelt advice. I’m a brother in my early 20s from Sweden, married to a Syrian Muslim sister, and we have a beautiful 3‑year‑old son. Alhamdulillah, her family accepted me right from the start. My own family, though… they never really warmed to our marriage and still say hurtful things sometimes. I always stand up to them, but I fear the pain on her side has already settled in deep. I embraced Islam about a year before we met, and I’m still working on my prayers, learning about the culture, family expectations, everything. I’m trying my best, even if I make mistakes. We’ve fought so long for this marriage-through my family’s rejection, the cultural differences, all of it. I believed we were strong because we kept choosing each other. But lately, it feels like she’s just… given up. She pulls away, avoids being near me, makes excuses. The other day she mentioned that our son looks exactly like me and nothing like her, and the tone broke my heart-like she regretted everything. Since then, she’s grown even colder. Sometimes she even hints that maybe I’d be better off with someone else. I tell her I love her, that I’m committed to doing whatever it takes, and I won’t let anyone’s opinions come between us. But she just nods and says she’s tired, and she won’t really open up. I’m the only one still fighting, it seems. I wonder if the cultural gap and my family’s rejection just broke something beyond repair. Has any brother or sister been through a similar situation, especially in an intercultural marriage? How can you start mending things when your spouse won’t talk? Any thoughts would help, in sha Allah. I don’t want to lose my wife and the life we’ve built together. (Small note: she even goes out of her way to stay busy so she can avoid being around me now.)
