My sisters boyfriend told me he liked me, I don’t feel the same way at all. I should tell my sister right?

He talked to me a lot when I was with him and my sister and he realised he liked me more and found me more attractive…… I told him I don’t feel the same at all

I’ve told her and she’s heartbroken but refuses to break up with him. Saying she could change him to be attracted to her. She doesn’t want me around them anymore which is gonna be awkward cause I live with her and he comes over.
Oh well, my sister is gonna get really badly hurt but I’ve done my part. (He just messaged me last night that my profile picture is really pretty and that he wish he meet me first….. I’ve blocked him now)
