The way Vansh has taken care of Ridhima and he expressed his feelings when she was not there says he cares for her. When Dadi asked him to confess his feelings to her, he is ready to do it also. However, when he was making her wear anklets the way he has seen her says he understood she is drawn towards him.
For a matter of fact, he may not hurt Ridhima in the way we are thinking. He is doing all this to make sure to bring the person behind Ridhima yet keeping in mind that Ridhima is just a pawn and she is pure from her heart. He might have understood whatever Ridhima is doing not because she belives but the person behind her manipulated her to do it. Therefore, he will be hurt when he learns about KABIR and as he is hurt he will hurt her too with his words and actions. Nonetheless, he will take care of her because it is his choice of making her his wife. Vansh knows for the fact that Ridhima was all set to leave the house and he was one the forced her to be his!
When coming to Kabir, today when Anurpiya said Ridhima is also falling in love with Vansh, the way he reacted was more like possessive boyfriend. Like how Tara was. She made sure Deep go near Arohi so her name can be wiped off, nevertheless, she don't want to lose Deep. In the same way, Kabir wants Ridhima in his life but in his own way.
P:S - Get well soon Rrahul!
