Religion and relationships

I've never really wanted to ask this and I have always tried to look pass it all, but would you love someone less because they don't believe in what you deeply believe in?

A little back story...

My ethnicity is Hmong and in my culture the daughter-in-laws do a lot for their family and the oldest son takes their mom in. Ive been with my husband for 5 years and hes the oldest out of his siblings. My MIL recently stayed in the ICU for about three days. I sacrificed my job (It was my own decision) to stay home and start taking care/monitoring her and go to all checkups. I love her so much and I care. When she was in the ICU I cried so much and had sleepless nights because I wanted her home (she lives alone because she wants to pray in peace). I stayed at the hospital to watch over her. My heart hurt. But she doesnt love me...because I don't go to church she doesn't love me. My husband and his siblings all got together the first day my MIL was discharged from the hospital, they told their mom to allow me and my husband to stay with her so we can take care of her closely and she said no. She doesn't call me her daughterinlaw either she just says "hey" and refers me as "that girl" "that person" to others.

I broke down to my husband and told him

"I can't take care of her she doesn't even let me. I have so much love for your mom but she doesn't love me..us..because we don't go to church. Religion is getting in between us and I'm trying to look pass it but when it shows that she doesn't want me around her it hurts me yet I'm still trying everyday. I've come from a loving family and to feel so unloved hurts me."

I cried so hard my husband could hardly understand me, he was EXTREMELY supportive of me though. He hugged me and kissed my forehead and told me I don't need to do anything I don't wanna do and he also said

"If my mom doesn't love us because we don't go to church and now she won't let us care for her then its her loss. Hunny I love you and if you feel this way I won't let you take care of her because you're hurting"

I love my husband. But I'm thinking about just going back to work full-time and tell his sister she needs to watch their mom. My culture also doesn't believe in outside homecare for elderly people so we keep our parents and take care of them until its their time to go.

If you got this far. Thank you.
