Feeling Stuck in My New Journey

Assalamu alaikum, everyone. I’m fairly new to Islam and still finding my way among fellow Muslims. It’s been about two months since I began praying, fasting, and trying to follow the Quran. I’m with a Muslim man, but I feel so guilty because my family doesn’t accept fasting; sometimes I feel awful because when my mom is around, I can’t fast as I’d like, and they just don’t accept Islamic beliefs. I feel trapped. My fiancé is very kind and a good person, but I’ve noticed he keeps to himself a lot. He doesn’t share much with me, even when I want to be there for him. It’s like he’s holding back his feelings about everything that’s happening, just keeping them inside. I pray to Allah to bless his life and make him happy, and honestly, I don’t know what to do. I end up crying in my room every night until I fall asleep. I can’t truly be myself, and it hurts that my fiancé might not feel supported enough. What can I do? May Allah bless everyone.
