<human>: Hi.

I'm only 17 and I'm protective of my siblings but i currently study abroad so i'm away from my family & the only way we talk is through facebook. My sister has a controlling conservative boyfriend, Lelele.

Yesterday I noticed all my sister's social media accounts are gone so i texted her what's happening, she said Lelele forced her to delete all her accounts because he wants her all by himself only. She told me he would be constantly in a phone converstaion w/ her even if she's working. 

I know i'm not in a place to say who she needs loves but I think he's starting to become an abusive boyfriend. My sister once told me that he forced her to wear a fucking hijab and he shouted at her after she disagreed. He's too much of a conservative it affects the way my sister lives & communicate with my family.

She doesn't want to break up w/ him because of shitty reasons like him calling her every morning and greeting her with a 'sweet hi' like they haven't talked in forever. Okay, sometimes Lelele is a good guy but she even reasoned he's only acting up because he's upset. I don't believe her.

I want her to stay away from him because what happens if this relationship moves forward? What if she disagrees to one thing he says? Will he beat her up? I can't confront this guy because I respect my sisters life but I know I have limits too.

Can you condense the text into a few key points?
<bot>: I can see my sister's conservative boyfriend starting to become abusive but my sister reasons that he's only acting like that because he loves her.
