Thinking about embracing Islam while married

Assalamu alaikum everyone. I grew up Catholic, went through all the sacraments, and then spent years kind of lost-not really believing in anything specific. But near the end of last year, with everything happening in Gaza, I finally picked up the Quran to read it. For the first time, I felt a real, powerful connection to Allah. Since then, I've been learning more about Islam and reading the Quran whenever I can. A close friend of mine, who was born Muslim, mentioned something that's been on my mind. She said that if I revert to Islam while still married, and if my husband doesn't revert as well, it could lead to ongoing difficulties, like being in a state of sin. I've been sharing what I learn with my husband, and alhamdulillah, he always appreciates it and thinks it's beautiful, but he isn't ready to take that step himself right now. I just wonder, would it really be so problematic? I love my husband deeply; we're committed to each other and have no intention of parting ways. Is it really so wrong for me to be Muslim if he isn't? I'm sorry if this isn't the right place to ask, but I could really use some guidance. Jazakallah khair in advance for any advice. Ramadan Mubarak to you all.
