Feeling troubled as my husband's connection to prayer has weakened, impacting our relationship

Assalamu alaikum. I need to share something that's been weighing on my heart and would really appreciate some guidance. During Ramadan this year, I felt my faith grow stronger. I made a commitment to pray regularly and on time, and by Allah's grace, I've been able to maintain that. But I've noticed something worrying about my husband-he seems to have completely stopped praying since Eid, except for Jumu'ah. When I gently remind him or ask about it, he either gives a vague promise or just avoids the topic. Once, he actually got upset and said if he had to pray, he wouldn't help with anything at home. He went to the masjid and stayed for Asr, Maghrib, and Isha prayers, which felt like an unusual reaction. Financially, things aren't easy for us, but one big reason my parents agreed to our marriage was because we all knew him to be someone who prayed regularly, attended the masjid, and engaged with the Quran. It's sad to see that he's stepped away from all that now. Honestly, this situation has changed how I feel inside. I don't feel at peace being close to him intimately anymore. I've never held back before, but now I'm really struggling with it and wondering if I should. I've searched online a bit, but it's a sensitive topic and I feel too shy to discuss it with family. I also don't want to cause him any embarrassment. Is it wrong for me to feel this way about intimacy in this situation? And how can I deal with this whole challenge in a good way? JazakAllah khair for any kind advice.
