If I thought that they would object, I wouldn't have asked. Mother is truly fond of you. I will let them know and you can tell me when you are arriving.
No, she's not. She is smart, enjoys a good book. She's your age, but sounds younger at the same time. In her time, she married a Muggleborn, which is why Bella is insistent that she marry now and I think she wants to spy on us. I think you and she could be good friends, and she needs friends that aren't her sister.
Maybe Mother can help you find a suitable person before Bella decides for you.
