Guidance on Embracing Islam While Staying with My Husband: Seeking Advice

As-salamu alaykum. I'm a young woman who was raised Catholic, and lately, my heart has been strongly drawn to Islam. Alhamdulillah, I've been married to my husband for five years. He's not really practicing his faith-he was raised Catholic but isn't active. I'm thinking of taking my shahada, but leaving him isn't an option; I love him deeply. I'm torn because I don't want to feel guilty or like a bad Muslim for staying with someone who isn't practicing Islam. I want to fully embrace the deen, but the thought of being apart from him breaks my heart. Any advice or Islamic perspective, especially from sisters who've been through something similar, would mean a lot. JazakAllah khair.
